Abicah compound ekwenzeni sokubumbela: ezizodwa zobugcisa

Abicah compound yinto enokwenzeka izinto lokuvelisa ngumngundo yeefosili Lifecasting kunye nezinye izinto nzima. Njengoko latex elulwelo, linika kulula, bhetyebhetye, imilo ephezulu inkcaneko. Kwakhona ke zinezibonelelo ezongezelelweyo - ebomini elide nokuzabalazela iikhemikhali yokubola. Le izinto Kucetyiswa ukuba imveliso iifom ixesha elide iisampuli ezibalulekileyo. jeli abicah kuba udaka zingenziwa kwangethuba ngaphantsi kwe ukungunda latex, ukuba usebenzisa i ehlanganisa "fast". Le ethile kuphela kukuba kuziindleko ngaphezu latex, kwaye elastic kunjalo, okukhokelela komsipha kunye nomonakalo.

Ukubunjwa abicah Material

Le nto ibandakanya lesilicon paste njenge isiseko kunye kuvala platinum, leyo ibalekisa lukhuni.

Xa ukwenza iindlela usebenzisa compound abicah ecacileyo, ebomvu, emthubi, abamhlophe kunye nezinye imibala. Le hardener inokuba mbala eyahlukileyo okanye enemibala.

Emva ukuxubana iinxalenye ezimbini kwigumbi lobushushu abicah Ukwakhiwa lube nzima kwaye lube inkangeleko yirabha. ixesha enganyangekiyo Umyinge yesininzi - phakathi iiyure 18-24, kodwa ixesha lukhuni ukuba kakhulu kuncitshiswa ngokusebenzisa ehlanganisa eliphezulu-yokusebenza.

Types of iikhompawundi abicah

Ezi zinto zixhaphakileyo irabha kusetyenziselwa ukuvelisa ngumngundo - oku RTV, RTV-2 kunye HTV. Ngokungafaniyo irabha RTV (igumbi ubushushu vulcanizing) abicah HTV ifuna iimeko ubushushu Ukuqinisa ngaphaya kwe-100 ° C.

Phakathi kwabo abavelisa abicah compound, wonke umntu uzama ukwenza ezininzi silicones kunye ehlanganisa kunye viscosity ezahlukeneyo, umbala kunye nezinye iimpawu.

Kukho iindidi ezimbini eziphambili ze RTV-silicones

1. Tin catalyzed silicones.

2. Silicones kwi ehlanganisa platinum.

Nganye kuzo ineendlela zayo kunye neengxaki. silicones Tin-catalyzed abiza kwaye kulula ukuyisebenzisa ngokubanzi. Zinelungelo viscosity echaphazeleka aphakathi, ngoko flow imveliso, eyajikeleza ngeenxa equleni. Ngokwahlukileyo koko, platinum zicinezelwa iikhompawundi amaninzi zifumaneka kwindalo, xa isalfure, inkcenkce, amine, ipholiyesta elisandula eyenziweyo, epoxy okanye urethane yerabha manqaku. Kwanasemva kokuba inqaku ukutyabeka acrylic lacquer abicah compound ukwenza platinum-Liqinisa phambi sulphur kunye asabela nomphezulu tinny. Oku kwenza ukuba akafanelekanga kusetyenziselwa izinto ezininzi zendalo. Noko ke, emva ukuqaqadeka, benayo imichiza liphezulu, ekuzakuqalwa kunye nokukwazi nobushushu-ukumelana, kwaye ngokubanzi sihlale dyondzisaka iminyaka emininzi. Ngokwahlukileyo koko, le silicones tin-catalyzed badla zaqina emva kweminyaka embalwa ukusetyenziswa iqale ukwahlula okanye ayikrazukanga. Ngenxa yezi zizathu, iqela silicones tin adla ngokusetyenziswa ukusebenza phantsi umthamo eyahlulayo. Kwaye platinum zisetyenziselwa umsebenzi obalulekileyo, ingakumbi ezininzi.

ixesha yokugcina

silicones amaninzi zingasetyenziswa ngempumelelo ukuya kwiminyaka emi-5 ukususela ngomhla ekuthengwe ukuba agcinwe kakuhle kwiziphathi zifakwe, kwindawo epholileyo eyomileyo. Kunjalo ehlanganisa balahlekelwe impumelelo yabo ngokukhawuleza, nokuba xa igcinwe kakuhle, ukuba zisetyenziswa kakuhle kwisithuba esingangonyaka.

phi na isicelo

Abicah RTV-2 ezimbaxa ezisetyenziselwa ukuvelisa iikopi ezininzi ze-mifanekiso. Ungowabo kwimveliso ipholiyesta, nentlaka epoxy, amafutha, ukutyabeka, amakhandlela, izinto zokudlala, iisepha, njl

Abicah compound "Pentelast" kukutya kwaye bakhuselekile. Abaxhamla kule nto ukuba bhetyebhetye kakhulu kwaye akukho umonakalo imveliso ngexesha ukususwa, ngumngundo irabha ezo zinokusetyenziswa ngokuphindaphindiweyo. Njengoko olu abicah ukutya-grade kunye ngumnxibelelanisi platinum, kunye nayo ungenza ngumngundo abicah ezibolile udaka ngenxa iikeyiki kunye muffins, iikeyiki kunye nezinye iimveliso confectionery.

Safety Note

Le abicah compound ndawo esha imveliso ekhuselekileyo xa zisetyenziswe ngokuchanekileyo, nangona kunjalo ehlanganisa kunye thickeners ibe yityhefu amehlo ulusu, Noko ke, la malungu omzimba lokukhuselwa.

Inkqubo ekudaleni ngumngundo

• Umphezulu ukopishe sampuli ukuwuhlamba degreased. Ukuba kuyimfuneko, eli kuzakuthothisa wasebenzisa amafutha, isisombululo ngesepha okanye petrolatum.

• Le izinto ngokugqibeleleyo ogalelwe, ekubeni kwenze ukuba kuyilwa ngexesha yokugcina.

• isikhongozeli Pre-ukulungele apho HAS umbono. Ngoko ke isikhongozeli inokuba indebe yeplastiki, ibhotile okanye ibhokisi. Kufuneka ube ezantsi ngqo kwaye omabini ngaphandle neentanda kunye nemingxuma.

• Kwisingxobo exutywe qho ecocekileyo kunye hardener de enobunzima eyohlobo olulodwa.

• Ukuze ukuqikelela isixa abicah efunekayo, kufuneka ukubala umthamo obuthululwayo, ukuze imveliso sele sigqunywa ngokupheleleyo. Enye indlela - unako kukugubungela nje ubuso mveliso, kunye imingxunya kunye nemingxuma, emva ukuqaqadeka ye abicah ukuba bazalise enye inxalenye, kule abicah mzekelo kwaye imali. Ukuze ukugubungela ngokufanayo le ndlovu, kungakuhle ukuba ugalele abicah okanye isetyenziswe amaqela amabini okanye ngaphezulu. Iqela lesibini libekwe phezu eqina kuqala, kodwa ancamathelayo. Uyakwazi ukusebenzisa igozi okanye ezinye izinto nokubethelela ukuba uzinziswe phakathi maleko, nto leyo eyenza ukuba kuvelisa uhlobo esiqinileyo.

• Le ehlanganisa zaye ezixutywe ngokwemilinganiselo kuxhomekeke kudidi abicah. Abanye babo usebenzise isiseko kukukhokela ratio 50:50. Ushu ingaba ngumatshini okanye ngesandla ngecephe okanye stick. Umntu akakwazi ukufumana inxaxheba elide kule nkqubo ayikho kwimizuzu ngaphezu kwe-2, lo gama nje le nkqubo uvelisa ezininzi amaqamza kulo mxube. Ukuze ukwazi ukuba ukungqinelana efanayo kwaphumela, kungcono ukuthatha umbala a hardener.

• Emva ukukhwezela umxube obegalelwe ngokukhawuleza kangangoko kunokwenzeka. Le izinto abagulayo kwimo yirabha kwisithuba seeyure ezingama-24. Kwiqondo lobushushu ngezantsi +23 ° ixesha C setting iya kuba elide.

Into ekufuneka ucinge

amaqamza kungancitshiswa ukuya nto, ukuba ngokuqalisa umxube imixube isabelo amancinci usebenzisa ngebrashi, isampuli awugubungele macala. Ngenxa yoko, ukurhoxiswa kwenziwa amaqamza nje kuphela kodwa ke ukucaca shape ulwandlalo. Emva ufaka umaleko obhityileyo kwemveliso sinyamalale ukuphumla kubushushu igumbi kude, kwada umxube ukhululekile umoya yaye akayi lukhuni. Ke ukuxuba inxenye eseleyo hardener kunye isiseko kwaye ifakwe ungqameko kwi imveliso ukuya imilo ogqityiweyo. Phantsi kweemeko laboratory, le nkqubo lula, njengokuba kubhaliwe lwenziwa ngoncedo imishini vuthululani ukungunda wawagalela kwaye khupha emoyeni. Xa iimeko komhlaba ziya kugungqiswa zisuswe, elinguwe evunyelwe komhlaba.

Ukuba isampuli Akukho imida yendalo ukuze kuthintelwe ukusasazeka kwe abicah ngexesha ukuthululwa, kuya kuba yimfuneko ukuba ukwakha udonga olubiyeleyo ngeenxa isampulu. Oku kungenziwa ngokusebenzisa nayiphi egalelwe ezifana ngamaplanga iinkuni, iibhodi, khadibhodi, njl njl Ukuqinisa uyitywine udonga itoti ngokusebenzisa ngcina tape ukuya abicah akuthethi avuze ngokusebenzisa noqhoqhoqho.

Isilumkiso! iintlobo ezithile abicah ukuze olumbhatshileyo kancinane, ezinye iintlobo zeengxondorha sokubumba yenziwe kuzo. Phambi kokuba umsebenzi kucetywa ukuba ukumvavanya ukuba kunjani na isampuli ayinamsebenzi phambi kokusebenzisa kwabo izinto ezixabisekileyo.
