I-coniferous plywood: iimpawu, ukuvelisa, ukumakisha. Plywood PSF

I-Plywood yinto yokwakha eyenziwe ngamacandwe enkuni (i-veneer) ihlanganiswe ndawonye.

Isici

Iipropati eziphambili zeplywood zixhomekeke kumthi owenziwe kuwo. Sekunje igama licaca ukuba i-coniferous plywood yenziwe ngeentlobo ze-coniferous (i-spruce, ipineyini). Uluhlu lwamacwecwe lulungiswe ukuze iifayili zilandelelana.

Impawu eziphambili zezi zinto:

• Indleko ephantsi.
• Ubuncinane ubuncinane bezinto eziphathekayo.
• Ukujongana nokutshintsha kweqondo lokushisa.
• Ubungqina bokuthutha.
• Amandla amakhulu ngenxa yobukho beendawo.
• Yilula ukuyisebenzisa (unokubona, ukubola, njl njl).
• Iphunga umsindo.
• Isebenza njengoluhlu lwe-thermal insulation.
• Umthi okhutshwe ngeemithombo zendalo, ezenza izinto ezichasene nokubonakala kwesikhunta nefungi.
• Ukuxhatshazwa ngokufanelekileyo kwimimandla enobudlova.
• Eyona nto ifanelekileyo ngenxa yesakhiwo esibonakalisiweyo somthi.

Izindlela zokwenza i-plywood

Kukho iindlela ezintathu:

1. Sawing. Ukuveliswa kwemveliso, izinkuni zinqunyulwa zibe zi-5 mm ububanzi. Ngale ndlela, izinto ezisetyenzisiweyo zisetyenziselwa ngokungazenzisiyo.
2. Ukucwangcisa - indlela eyongeziweyo yokonga, evumela ukufumana i-veneer ngobukhulu be-3.5 mm.
3. I-Plywood grouting yindlela apho ama-veneers ane-1.2 ukuya ku-1.9 mm atholakala.

Yiyiphi iplywood e bhetele: i-birch okanye i-coniferous?

Ukuveliswa kwemveliso, iintlobo ezahlukeneyo zeenkuni zingasetyenziswa : iintlobo ze-coniferous kunye neziqhamo. Iipropati zezinto ezifunyenweyo zixhomekeka, ngokuqinisekileyo, kwizinto eziluhlaza. Iintlobo nganye zineenzuzo kunye nezibi.

I-plywood yeentlobo ze-coniferous iqulethe inani elincinci lezinto. Izinto ezenziwe nge-larch zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zizinzileyo. Ukufumana izinto ezinokude ngakumbi kukukhetha i-plywood kwi-birch.

I-Veneer eyenziwe nge-birch ine-tint yokukhanya kunye nokubonakalisa kakubi. I-Coniferous amadwala, ngokuchaseneyo, imnyama kwaye inomzekelo omhle ocacileyo.

Umthi weConiferous uhlanganiswe neenkunkuma zemvelo. Ngenxa yoko, izinto ezenziwe kuzo azibonakali zingabonakali kwi-mold kunye nefungi. I-coniferous plywood yinto engabonakaliyo yokwakha.

Ukumakisha

Umgangatho wezinto eziphathekayo kuxhomeke kakhulu kwi-glue esetyenziselwa ukudibanisa iziqendu zobunini. Kuxhomekeke kule nto, i-plywood i-coniferous ineempawu ezininzi:

• I-FBA yiyona mveliso ephezulu kakhulu. Yenziwa kunye ne-albuminasein glue. Oku kwenza izinto ezinobungakanani bendalo. Kodwa esi sixhobo asikwazi ukuma umswakama. Faka isicelo kuphela apho ukhuseleko lwe-ingress yamanzi.

• I-PSF - uphawu oluthandwa kakhulu, olwenziwa nge-phenol-formaldehyde glue. Inamandla ngokwaneleyo kwaye angenawo amanzi.

• I-TV ye-FSF-ihluke kwi-brand FSF yokungeniswa kunye nabazilawuli bamatangatye. Ngenxa yoko, i-plywood coniferous yale ntlobo ine-inflammability ephantsi.

• I-FC ikhiqizwa ngoncedo lwe-urea glue, eyenza loo nto ibhalwe ngokugqithiseleyo. Isetshenziselwa ukuvelisa ifenitshala, izitya, izakhiwo zangaphakathi.

• I-FB yinyameko yokunyusa, ingabonakaliswa kwimeko enobundlobongela. Ungayisebenzisa nangaphantsi kwamanzi. Oku kufezekiswa ngokudibanisa iziqulatho kunye ne-bakelite glue kunye nokufakelwa ukungeniswa kwempahla.

• I-plywood yemidlalo ye-BS, yafumana igama layo ngenxa yokusetyenziswa kwayo kwi-aircraft kunye nasekwakha iinqanawa. I-Veneer ihlanganiswe kunye ne-bakelite-soluble glue. I-plywood ye-coniferous yale mpawu ayizinanzi, inamandla, iguquguqukayo kwaye inganyangekiyo kwimeko enobundlobongela.

• I-BV inesakhiwo esifanayo ne-BS. Ukwahlukana kuphela kukuba izinto ezikulo mqondiso zinoyika ukwanda kwamanzi (zenziwa ngoncedo lweglue).

Zonke iintlobo zeplywood zihluke ngokubanzi. Kuxhomekeke kule nto, inokuthi ibe yintlobo ezintathu: unpolished (NS), ngokugaya enye (Ш1) kunye nomhlaba kumacala amabini (Ш2).

FSF

I-coniferous plywood i-FSF ithandwa kakhulu ekwakhiweni kweendawo zamashishini kunye nezoshishino. Ukuxhatshazwa kwamanzi kufunyanwa ngokufaka ingqalelo kwiindawo ezineengqungquthela ezingekho phantsi kwe-formaldehyde. Emva kokungeniswa kwempahla, iziqulatho zethambisi zityhefu phantsi komshicileli kwiqondo lokushisa eliphezulu.

Kuvumelekile ukuba i-GOST ihlukanise inani elithile le-formaldehyde kunye ne-phenol. Oku kwenza kube nzima ukusebenzisa i-plywood ngqo ngaphakathi kwendawo.

Iifayile zeplywood zeplywood zineendawo eziqhelekileyo: 1.22 x 2.44 m, 1.25 x 2.50 m, 1.525 x 3.0 m, 1.525 x 1.525 m Ngesikhathi esifanayo, ubunzima buhluka phakathi kwe-4-30 mm.

I-plywood yemveliso ye-coniferous yamanqaku ethi ФСФ ifumane isicelo esikhulu. Iindlela eziphambili zokusetyenziswa kwazo zi:

• Ukwakhiwa kwexeshana ngexesha lokwakha.
• Ukutshintshwa kwezinto.
• Njengokugqithwa phantsi kwephahla.
• Xa sakha imoto, iimoto kunye neenqanawa zokuhamba.
• Ukudalwa kwegadi kunye nefenitshala yelizwe.
• Ukwakhiwa kwefomu (izinto zingasetyenziswa ngokuphindaphindiweyo).
• Njengemveliso eluhlaza kwimveliso yezinye izinto.

I-Plywood yinto engabonakaliyo kwaye isakhiwo esiphezulu esiye sithandwa kakhulu kwiimarike ixesha elide.
