Olee otú ịhọrọ mama ka plastic

Iche plastic nwere ọtụtụ, ma ha niile na-ada abụọ dị iche iche: thermoplastics na thermosets.

Ya mere, n'ihi na elu-edu mmezi nke plastic ngwaahịa mkpa ịmata ihe ụdị plastic ha na-mere, ọ ga-enyere iji chọpụta ihe mama ka gluu na plastic nke a ụfọdụ ndị. Ọbụna a yiri na-adịghị mgbagwoju n'ezie nwere aghụghọ ha. Dị ka ihe atụ, plastic ụmụaka nwere ike idozi eji a ot soldering ígwè, ma n'ihi karbalitovoy efere ntụ mma iji nyagide maka plastic ika BF-2. M gwa Abigel tụlee ma iche iche ọzọ, iji ghọta ihe nile ụzọ aghụghọ nke bonding kụwaa akụkụ.

Ndozi na gluing nke thermosets

Akpọkwa a ụdị plastic ike nro, ịlọ re-ụdị, ọ bụrụ na ihe a na-agbajikwa, ọ nwere ike na mama. Si dị otú ahụ plastik ime efere, senti ite, buttons, ikpe maka igwe na ese foto, sockets na plọg. All n'ime ihe ndị a nwere ike mfe agbaji ma ọ bụ ịgbawa ka a daa, ha ga-mkpa ịrụzi nyagide maka plastic ika BF-2 na BF-4, nakwa dị ka nitrocellulose, polyvinyl chloride na polyvinyl acetate adhesives.

Bonding a rụrụ ọtụtụ nkebi:

1. Mgbaji ọkpụkpụ na-ọma kpochara si ájá na unyi, na na na degrease. N'ihi nke a gbajiri agbaji nkọwa mma itucha na mmiri ọkụ na ncha.
2. Na-akpachara anya Fikiere site mama etinyere n'elu a mkpa oyi akwa na mịrị amị ya otú ọ ga-arapara mkpịsị aka.
3. The abụọ nyagide oyi akwa na-na-etinyere na ma na-ebupụta na-ekwe ka ada 1-2 nkeji, mgbe nke ahụ akụkụ na-jikọtara ma dọba n'okpuru pịa.
4. The ihicha usoro dịruru 3-4 ụbọchị.

Mmezi na bonding nke thermoplastics

Plastics otu thermoplastics mfe ịrọ arọ site elu okpomọkụ na ike-agbazekwa n'okpuru edinam nke ụfọdụ solvents. Nke a plastic na-eji na imewe nke agụmakwụkwọ itienna, ncha efere, combs, ntem osisi na ụmụ ụmụaka. Na mbụ, ihe ndị a na-mere nke combustible plastic celluloid, ma ugbu a ọ na-esiwanye dochie na-abụghị flammable cellulose acetate. Na ya na ndị ọzọ plastic soluble na acetone. Nyagide nke ụdị nwere ike nke plastic naanị, a ga-achọ na-arụ ọrụ na chọrọ plastic ụdị mgbaze (2 akụkụ) na celluloid ibe (1 akụkụ). The Efrata na-agwakọta ma echekwara na a akpa na a uko mkpuchi.

Hụ thermoplastic iche thermosets, ọ nwere ike na-emejuputa atumatu na ọtụtụ ụzọ:
