Pipe Polyvinylchloride: ukuyinyusa iimpawu, iimpawu nezilinganiso

pipe Polyvinylchloride ngenxa ubunzima ephantsi kunye iintlobo ezinye iimpawu yobugcisa enye izisombululo ezifanele ngokubekwa iinkqubo sabelo ezahlukeneyo. umsebenzi wofakelo kunye neengxaki, kodwa kufuneka uyazi into features na umbhobho PVC. Phakathi iimpawu ezongezelelweyo iimveliso ezichazwe ziphawulwe:

• ubomi inkonzo ende;
• ixabiso afikelelekayo;
• ubunzima low;
• ukufakwa lula.

ubunzima Low kuvumela ufakelo ngaphandle kokusebenzisa zokubopha ezizodwa. Ukongeza, i-isixhobo ebiza asifuneki, unako ukubeka yombhobho ngokwabo, ngaloo ndlela zokonga imali yabo. Njengoko omnye iingenelo ezibalulekileyo kufuneka anikezele akukho mathuba engqalene imibhobho intsimbi kunye nentsimbi.

Kungenxa yoko le nto umbhobho data liya kusetyenziswa kwiindawo ezininzi zezinto ezenziwa luluntu, ukukhuphela iimveliso kwezinye izinto. Ngapha koko, ukuba okuhlala, musa ukunika isondlo kwaye kuyabiza, kwaye uwafake ngeendleko ezincinci.

iimpawu technical

Imibhobho Polyvinylchloride aneempawu yokusebenza ebalaseleyo. Bona ebonakala thunzi ngumkhinkqi eliphezulu, apho amanqaku bayakwazi ukuba bangenele uxinzelelo lwangaphakathi umoya 120. imibhobho abamelana kakhulu deformation thermal. Xa itshiswe, ityhubhu elongates% 5 kuphela umqulu yokuqala. Ngokumalunga iqabaka, i PVC ayikho nje ukumelana kwiimpembelelo ezinjalo. Ngoko ke ukubekwa kwemibhobho le nto kufuneka ikhatshwe usambathisa thermal.

Le umbhobho akufuneki zipholile ngezantsi -15 ° C. Imibhobho PVC ahluka uzinzo ayilunganga kangaka thermal. Material uqala ukuphulukana ukuqina yayo xa isetyenziswe lobushushu ngentla 78 ° C. imiphezulu zangaphandle nezangaphakathi ukuba uburhabaxa ubuncinane, oku kuthintela etyekezwa up yalo mbhobho. izinto lokhwakhiwa ngaka usulelo ukukhanya umxhelo. Hlangana umbhobho PVC transparent olunikezelwayo kangangoko kunokwenzeka, kodwa kumaxesha amaninzi weemveliso ezinikezelweyo kwifomu epeyintwe. Kodwa ukwimeko enjalo ekwaziyo ukumelana PVC UV ngcono kunezinye iintlobo zeplastiki.

Amanzi ngexesha yothutho kumbhobho PVC akatshintshi iipropati yayo. Oku kubonisa ukuba olu hlobo lonxibelelwano ingasetyenziselwa zokumpompa nje kuphela zobugcisa, kodwa okusela amanzi. Izinto eziluncedo ezingundoqo imibhobho enjalo abahlukunyezwa inertia ngumkhinkqi eliphakathi kwaye ophezulu kudluliselwe circumferential evumela ukuba ukufaka imibhobho eliphezulu-ingcinezelo.

Ngokubhekiselele kwiinkqubo amanzi ashushu, lo chloride Polyvinyl ezisetyenziswa kuzo akunakwenzeka, kuba umda lobushushu nokusebenza yombhobho kuphela 40 ° C. Nakuba kwiinkqubo pipe non-ingcinezelo ezifunwa yi kwezinye izinto, phakathi kwabo kukho imfuneko yokwenza oko kunika Ebubanzini bodonga minimum kunye ngobuqhophololo eliphezulu kumphezulu embilwini. Ngokuphathelele balo babulingana nesandla, oko ekungabonini ukusuka kwi 1.5 ukuya ku-6 mm. Le propati zikwazi ngokubekwa inkqubo amdaka ubude bale. Ngenxa yoko, ngaba inkqubo ingafumaneka necandelo encinane yombhobho, nto leyo uthathe isixa elininzi inkunkuma.

Ezinye iimpawu imibhobho PVC non-uxinzelelo

pipe PVC xi Non ingafakwa kwaye uqhagamshele omnye komnye nge amakhonkco uphawu. Loo ndlela engathethekiyo kunokwenzeka xa usebenzisa iinkqubo zangaphakathi nangaphandle. imibhobho Non-ingcinezelo abe kwisokethi anquma kwelinye icala, netoti apho zingaqala mm 63 ukuya 315. Imibhobho ezinjalo kungenziwa eziqhutshwa kwi ezona xi yokusebenza ka-0,63 MPA. Noko ke, umbhobho ngokwayo ikwazi kwazo ukuya ku-20 MPA.

Iimpawu imibhobho uxinzelelo ezenziwe polyvinylchloride

Imibhobho PVC PVC kunokuba nkqu nentloko ingcinezelo. Banalo ikhono uye uxinzelelo umxhelo, ngoko ukwakha imibhobho iimveliso epholileyo. Bona ufana umsi, kodwa ekugqibeleni zibe ukuqina ekhethekileyo kwisokethi.

Ububanzi PVC uhlobo kumbhobho xi ziyahluka ukusuka mm-10 ukuya kwi-90. Ukungqinelana GOST uyakwazi ukubala 11 ngobukhulu yokuqala. Ubuninzi Uxinzelelo yokusebenza 2 MPA. Ukuba eli xabiso wedatha, umgca kulu i abakwazi ukumelana umthwalo. Ukuthengiswa ingabonwa ngaphezulu kunye nemibhobho ngaphandle isokethi, kusetyenziswa kwindibano nkqubo ezi ntlobo zilandelayo lwezilinganisi:

• uphawu;
• intambo;
• ngcina.

Netoti ityhubhu agudileyo isusela ukusuka mm-10 ukuya 315. iimveliso ezinjalo kungenziwa ingcinezelo nje kuphela kodwa kwindlela esesikweni engeyiyo eye-ingcinezelo kusetyenziswa.

Incence PVC tube: Properties

pipe Polyvinylchloride incence uyakwazi lokuzimela ucimayo, yinto ephambili leyo yenye yeendlela ezibalulekileyo ukuba ngokubekwa ingcingo. I-pipe akabi, kodwa linyibilike kwaye engamabhodlo, iyabuna ngokupheleleyo kwaye ime umlilo. imibhobho ezinjalo eqinile, baye vlagoottalkivayuschey ngokuhlaziya kumphezulu enganyangekiyo loo nto ezinokudla, ulahlekelwa iipropati yaye aluthathi zonakalisa ngethuba lomjikelo wobomi.

Ngemibhobho zombane incence PVC ezi thermoplastic. Xa bazifake obushushu abasabela kancinane. mode Ubushushu yokusebenza ziyahluka ukusuka -20 ukuya +80 ° C. Njengoko kokufaka, oko kufuneka kwenziwe ngaphandle kubushushu ka -5 ukuya +60 ° C. Phakathi kwezinye izinto, izenzo chloride Polyvinyl njenge Heating, nto leyo ebonisa ubuchule layo ubushushu.

Iimpawu obandayo

umgca Pressure iqala kwaye iphela ivela kumthombo impompo. conduit Pressureless ekuqaleni a siphon-uhlobo PVC, ngoxa ekupheleni - magciwane, ingontsi emhlabeni. To connect itanki yokubolisa elizenzekelayo kuyimfuneko kukuxhobisa umgca emide, neya kubandakanya izifakelelo kunye nemibhobho. Inkqubo eqhubekayo ukuze yenziwe ngomnye iindlela ezintathu. Eyokuqala ibandakanya ukusetyenziswa kwisokethi, wesibini - iwelding abandayo, ngelixa lesithathu - izifakelelo azinamsonto.

Iimpawu Ukufakelwa kwemibhobho yogutyulo ezenziwe PVC

umbhobho wamanzi amdaka PVC kukuzishumayela iteknoloji ethile. Nezinto kwinqanaba lokuqala kufuneka lungqanyaniswe omnye komnye zize zizitshekishe, nokuba Amathambeka engile. Ngaphezu koko kwenziwe le yophawulo, ukuba ulahlekile inani elikhulu sineendidi. Iziqalelo inamathelene, kubalulekile ngeli thuba ukukhangela ukuba umbhobho owongozelelweyo ukuya kwisokethi 2/3 ngaphandle umgudu.

Ngenxa yobunzima welungu ethe kunye inamehlo okhethekileyo. Ukuze kuphuculwe amaziko adhesion of conjugation kufuneka roughened. Yakuba iglu uyasetyenziswa, kunokwenzeka ukuba xa kufanelekile. Emva kokuba ufakelo lugqitywe ufuna ukukhangela le nkqubo ukuba akukho zindawo zivuzayo. Ukuba kukho ukuvuza elibhaqiweyo, umsebenzi wofakelo lwaqhutywa ngempumelelo.

Assembly kwi kwezisekelo

Imibhobho PVC (GOST 51613-2000) kufuneka iqokelelwe kwi ifanele. Kuba T-sifuba elinye isebe ukuya kwenye tee izixhobo ezifunekayo. Nezisekelo kufuneka abekwe ikhonkco lokutywina kunye nesiphelo egudileyo umbhobho ukuseka kwisokethi uphawu. I ring uya kuzigcina nendawo egudileyo uyitywine joint.

Wahlanganisa usebenzisa welding abandayo

Ukufakelwa nge welding umkhuhlane yenziwe ngexesha yokubekwa yombhobho, xa kuyimfuneko ukubonelela conjugation emboxo okanye bar. Kwimeko yokugqibela, ityhubhu ngakumbi, xa le ngcina wokuqala singasuswa izixhobo kunye nemibhobho egudileyo.

Wahlanganisa usebenzisa i iglu ngolu hlobo lulandelayo. Inyathelo lokuqala kukuba kunqumla ekupheleni ukuba uyenze, okt ukuba ukucoca nokususa Isipha. Master kufuneka uhlole ubunzulu ubhaptizo kunigqibela ubuso ogudileyo kunye nokufaka elandelayo.

Emva koko, ubuso engaphandle isiphelo ubuso ogudileyo iphathwa enesithuba nazinkinga kunye namalunga isusiwe. Phezu engaphakathi kufanelekile socket kunye nemfuneko ukuphumeza inyathelo efanayo. Xa ukucocwa lwenziwa phezu komhlaba ofanelekileyo kunye nombhobho kufuneka asebenzise i kulu ezizodwa, apho kufanele ukuba lubandakanye umphezulu embindini kunye nesabelo ibhalwe. Xa Inyathelo lokugqibela eziyimfuneko tyhala umbhobho ukuya kwisokethi okanye isilinganisi ukuba amakishe nobunzulu, ngoko phendula malunga axis, iya kuvumela ukuba isasaze kweziyobisi enamathela ngokulinganayo.

isiphelo

Ukuba ugqiba ukuba uthenge imibhobho PVC, ixabiso le mveliso kufuneka ube nomdla. Umzekelo, umbhobho incence lokujongana nokufakelwa zingathengwa ngenxa 10,67 engange. nganye square metre. Kule meko sithetha into kabani ubukhulu yi-25 mm. Cable ezingatshiyo umgca lemibhobho PVC incence iya kuxabisa 16,73 engange kubathengi. nganye square metre. Kwaye nanku wombhobho kulula engqongqo nokufakelwa ukuba bathole 17.15 engange. nganye square metre.

Intambo line ezingatshiyo, esibonakala ubunzima ukukhanya ukuqina, uya kuhlawula 26,89 engange. nganye square metre. ububanzi bayo 25 mm. iyawulwa umlilo ingqamana iiklasi E60-E90. Ukuthengwa tube lokujongana nokufakelwa banokuba ezisebhokisini - ibheyi (25 m). Imveliso unalo uphenyo kwaye ubukhulu pipe 25 mm. Thenga PVC wombhobho olu hlobo unokuba 333,38 engange. pack ngalinye.

ncomo Consumer bathi ukufaneleka kwemibhobho PVC mkhulu kakhulu neengxaki. Ukuba zezona ukufudumeza, ucoceko njalo njalo. D. Abasebenzisi abaye ubazuzileyo kumbhojana PVC, andizohlwayi ukhetho wam.
