Indlela ukukhetha le ngcina ukuze yeplastiki

Iintlobo zeplastiki abaninzi, kodwa bonke baya kuwa zibe ngamaqela amabini: thermoplastics kunye thermosets.

Ngoko ke, ngokuba ezikumgangatho ophezulu nokulungiswa iimveliso zeplastiki kufuneka ukwazi ukuba yintoni uhlobo zeplastiki zenziwe bona, oko kuya kunceda ukuqinisekisa ukuba kulu ukuba uncamathelise yeplastiki yeqela elithile. Nakuba kule ebonakala gingxi unabo abagwenxa. Umzekelo, iithoyi zeplastikhi ungalungiseka ngokusebenzisa ngelotha intsimbi eqhelekileyo, kodwa karbalitovoy ieshtreyi kungcono ukuba usebenzise iglu ukuze BF-2 brand zeplastiki. I Sicebisa ukuba siqwalasele omabini amaqela ngakumbi, ukuze siqonde zonke ubuqili iinxalenye nimanyane ziye.

Ulungiso kunye kuncanyatheliswe of thermosets

Iinjongo zale hlobo zeplastiki ayikwazi athambe, ziyanyibilika kwaye kwakhona form-, yaye ukuba loo nto yaphulwe, ungakwazi glue kuphela. Ukususela iiplastiki ezinjalo wenze izitya, iingqayi isiqhumiso, amaqhosha, amatyala ngenxa phones kunye iikhamera, neziseko kunye iiplagi. Zonke ezi zinto lula ukwaphula okanye ngothanda kukuhla, yaye kuya kufuneka alungise ngcina ukuze BF-2 zeplastiki brand kunye BF-4, kwakunye nitrocellulose, Polyvinyl chloride kunye Polyvinyl yokuncamathelisa acetate.

Ekwakheni ubuhlobo oluqhutywa kwizigaba ezininzi:

1. Ukwa ku icocwe ngenyameko ukusuka nothuli nobunye ubumdaka, uze uqiniseke ukuba degrease. Ukulungiselela le njongo iinkcukacha ezaphukileyo pula ngcono ngamanzi ashushu nesepha.
2. Ngelo komiswa ngononophelo yi kulu isicelo kumphezulu umaleko obhityileyo wome ukuze ayiyi babambelele iminwe.
3. Le ngcina Umaleko yesibini lisetyenziswa kwi zombini imiphezulu kunye avunyelwe ukuba eme ngeenyawo imizuzu 1-2, emva koko malungu ezidibeneyo phantsi eendaba.
4. Inkqubo yokomisa ihlala iintsuku 3-4.

Ukulungiswa kunye lib thermoplastics

lula thermoplastics iiplastiki iqela wambongoza obushushu aphezulu kwaye kunyibilika phantsi isenzo izinyibilikisi ezithile. Le weplastiki ezisetyenziswayo xa kwenziwa imveliso ezibayeni zokubhala, isepha izitya, bamanqatha, intlekisa izakhelo kunye zokudlala abantwana. Ngaphambili, ezi zinto zazenziwe celluloid zeplastiki ezinokutsha, kodwa ngoku liya indawo neselulosi non-ezinokutsha acetate. Ke yena omnye lo zeplastiki enyibilikayo acetone. Ngcina yolu hlobo ingenziwa lweplastiki wedwa, oku kuya kufuna ukusebenza kwi uhlobo olufunwayo zeplastiki ezinganyibiliki (amalungu ama-2) kunye neetships celluloid (1 inxalenye). Izithako zixubene kwaye zigcinwe kwisingxobo enesiciko tight.

Ekwakheni ezahlukeneyo thermoplastic ukusuka thermosets, oko kuphunyezwe ngeendlela ezininzi:

1 indlela

iindawo bacanda yokuqaba ukusebenza isinyibilikisi zeplastiki, silinde de ekupheleni yokwahlulahlula uya kuba incangathi, ngoko dibanisa gqo izinto uzibeke phantsi eendaba ukugqibezela lukhuni.

indlela 2

Kuba kuncanyatheliswe ukusetyenziswa nitrocellulose ngcina ukuba brand zeplastiki "Mars", "C-1" kunye "MC-1".

3 Indlela

Iikona ukuba budinga ukuba utshiwe ngaphezu ukukhanya isicelo kuso okanye etyhidiweyo, ebezikuyo iinxalenye edge wathamba uxhulumeneyo. Xa amalahle kuyimfuneko ukuthintela ukutsha, ukuba umthungo wayengekho mnyama.

Ngoko ke, ukuba bayihlaziye nto ihlala ixesha elide waza baphulukana ifomu, kuyimfuneko ukuba ukhethe iglu ilungileyo olu hlobo zeplastiki. Ngapha koko, kuphela ngcina okhethiweyo kakuhle uza kubonelela uxhulumaniso oluthembekileyo.
