ABS plastiki: makhalidwe, ubwino ndi kuipa

Zida zimenezi, monga abs-pulasitiki, zimakonda kwambiri komanso zimafuna kupanga magetsi ambiri ndi zipangizo zamakono. Pankhani imeneyi, mosiyana ndi mapulasitiki, nkhaniyi ili ndi zizindikiro zogwira ntchito, zomwe zimafotokozedwa ndi kuwonjezeka kwa kukana kwa mawonekedwe ndi kutetezedwa ku zinthu zachilengedwe. Kodi nchiyani chomwe chiri chenicheni cha abs-pulasitiki, ndipo ubwino wake ndi chiyani?

Nkhani

Zinthu zimenezi ndi thermoplastic, resistant resistant resin, yomwe imatchedwa "acrylonitrile-butadiene-styrene copolymer". Zinthu izi zimakhala zofanana ndi pulasitiki. Maonekedwe ake kawirikawiri amapezeka ndi chikasu chachikasu. Komabe, mu msika wa mdziko, abs-pulasitiki nthawi zambiri imapezeka m'magalasi oonekera. Koma mu mthunzi uliwonse uli kale utoto, mulimonsemo nkhaniyi imathandizira kwambiri kuyaka mitundu, ngakhale ili ndi mthunzi wina.

Chifukwa cha kuphatikiza kwa butadiene ndi acrylonitrile zipangizo ndi styrene, pulasitiki pepala abs ali mkulu mphamvu ndi zotanuka katundu. Choncho, akhoza kusungunuka mu mawonekedwe ovuta kwambiri koma osataya zizindikiro zake zogwira ntchito. Choncho palibe pulasitiki ndi imodzi mwa zipangizo zomwe zimagwiritsidwa ntchito popanga ndi ulimi. Mwa njira, mu mafakitale amapezeka mwa mawonekedwe a pellets ophatikizana. Pazifukwa zawo, makampani ndi makampani amapanga mapangidwe osiyanasiyana omwe ali a kalasi ya ma polima apadera.

Dzina la plastiki abs?

Makhalidwe a nkhaniyi samasiyana kwambiri kuchokera kwa wina ndi mzake, komabe, ngakhale izi, ku Russia zinalembedwa mayina angapo. Zithunzi zofupikitsa "ABS", "ABS", komanso maina osiyanasiyana asayansi monga "Copolymer acrylonitrile, styrene ndi butadiene" kapena "copolymer ABS".

Ubwino

Pulositiki yamapulosi imakhala ndi ubwino wambiri poyerekeza ndi mitundu ina ya zipangizo zamapulogalamu. Choyamba, ndiko kukana kwake kwa alkali, mafuta, mafuta ndi ena amwano. Ndipo ngati mitundu ina ya pulasitiki ikhoza kusungunuka kapena kutayika pansi pa chikoka chawo, copolymer ya ABS imakhala yolimba kwa nthawi yaitali. Kuwonjezera apo, pamwamba pa nkhaniyi ndi yosalala komanso yowala. Chifukwa cha ichi, pafupifupi mafoni onse amakono amapangidwa ndi pulasitiki ya ABS. Panthawi imodzimodziyo pali ma polima opangidwa ndi matte ndi zipangizo zomwe zili ndi pepala lapadera.

Kuipa

Zina mwa zovuta zazikuluzikuluzi ndizomwe zimakhala zotsimikiziridwa ndi ultraviolet miyezi (zina zimakhala zowopsya zotsatira za benzene, acetone ndi ethyl kloride), zomwe zingayambitse kutuluka pamwamba. Mosiyana ndi polystyrene, pulasitiki yotereyi ili ndi malo otsekemera magetsi. Komabe, kupezeka kwa zofookazi sikumamulepheretse kutenga molimba mtima mndandanda wa zida zogwiritsa ntchito polemba mapulasitiki osiyanasiyana.
