Indlela ukukhetha glue kuya plastic

Izinhlobonhlobo plastic abaningi kangaka, kodwa zonke awela amaqembu amabili: thermoplastics futhi thermosets.

Ngakho-ke, i-eliphezulu ukulungisa imikhiqizo plastic kudingeka wazi ukuthi iyini uhlobo plastic zenziwa, kuyokusiza ukuba unqume ukuthi yini glue ukunamathisela plastic leqembu elithile. Ngisho nakuleli ezibonakala ayinzima empeleni babe namaqhinga abo. Ngokwesibonelo, amathoyizi wepulasitiki kungenziwa lilungiswe usebenzisa ezivamile nokunamathisela ngomthofu yensimbi, kodwa karbalitovoy isitsha somlotha kagwayi kangcono ukusebenzisa ingcina for plastic brand BF-2. I ukuphakamisa ukucabanga kokubili amaqembu, ukuze baqonde yonke ubuqili kunenze nisondelane waphuka izingxenye.

Ukulungiswa bese gluing ka thermosets

Izinto lokhu uhlobo plastic ayikwazi ukuthambisa, ancibilike futhi kabusha ifomu, futhi uma siphukile into, it can glue kuphela. Kusukela amapulasitiki ezifana izitsha, amakha izimbiza, izinkinobho, amacala amafoni amakhamera, nezinyawo futhi Imigudu. Zonke lezi zinto kalula aphule noma crack ukuba ukuwa, futhi kuyodingeka ukulungisa ingcina for plastic brand BF-2 kanye BF-4, kanye nitrocellulose, polyvinyl chloride futhi polyvinyl acetate anamathelayo.

Ubuhlobo obuseduze wenziwa ngezigaba eziningana:

1. Ukwa is bahlanza ngokucophelela kusukela izintuli nokungcola, futhi qiniseka degrease. Ngenxa yale njongo imininingwane eziphukile uxubha kangcono ngamanzi ashisayo nensipho.
2. Ngezinye omisiwe ngokucophelela glue isetshenziswa ebusweni ungqimba elincanyana yomiswa ke ngakho ngeke unamathele iminwe.
3. Eyesibili ingcina ungqimba futhi sisetshenziswa kuwo womabili evele futhi bavunyelwe ukuba ume imizuzu 1-2, ngemva kwalokho izingxenye ehlangana futhi ibekwe ngaphansi cindezela.
4. Inqubo omiswe ihlala izinsuku ezingu-3-4.

Ukulungisa kanye kunenze nisondelane ka thermoplastics

thermoplastics Plastics iqembu sashintsha kalula lokushisa eliphezulu futhi kungaba zincibilike lapho isenzo kumakhemikhali awuketshezi ezithile. Lokhu plastic isetshenziswa womshini zokubhala izibaya, insipho izitsha, amakamu, umbukwane ozimele namathoyizi zezingane. Ngaphambili, lezi zinto zazenziwa ezivuthayo plastic Celluloid, kodwa manje uya sithathelwe indawo okungezona oluvuthayo cellulose acetate. Futhi yena nabanye plastic oncibilikayo acetone. Yesigcilikisha yalolu hlobo ingenziwa plastic wedwa, lokhu kuzodinga ukusebenza wayefisa plastic uhlobo kuphela (izingxenye 2) and chips Celluloid (1 okuyingxenye). Izithako axutshwa futhi agcinwe endaweni esitsheni ngesivalo ezihambisanayo.

Ukusondelana ehlukene Thermoplastic kusukela thermosets, kungashiwo lwenteke ngezindlela eziningana:

1 indlela

izingxenye oqoshiwe lubricating nomthelela uketshezi plastic, bese ulinda kuze yokuhlukanisa imiphetho iyoba okunamathelayo, bese ufaka i-ayithemu wafaka ngaphansi cindezela ukuqedela ukuqina.

indlela 2

Ukuze gluing ukusetshenziswa nitrocellulose ingcina umkhiqizo plastic "Mars", "C-1" futhi "MC-1".

3 Indlela

Emaphethelweni ukuba eziboshiwe abathukuthelela ngenhla ukukhanya sisetshenziswa nalokho noma insimbi ezibunjiwe, tapho sashintsha onqenqemeni izingxenye axhunyiwe. Lapho amalahle kubalulekile ukuvikela esivuthayo, ukuthi umphetho wayengekho ebumnyameni.

Ngakho, ukulungisa into ihlala isikhathi eside futhi akalilahlile ifomu, kubalulekile ukukhetha ingcina kangcono lolu hlobo plastic. Phela, kuphela ingcina kukhethwe kahle izonikeza ukuxhumana okuthembekile.
