Txoj Hlub Siv Lub Polyamide Rau Kev Tshuab Txhaum Tshuab

Polyamide roob tshiab yog qhov siv khoom uas tau los ntawm kev roob tshiab los ntawm kev lag luam lossis kev siv khoom tshiab thiab roob tshiab rau hauv polymer granules tshiab. Qhov kev pib siv khoom tshiab no muaj txoj caij heev rau kev txo cov cuab yeej tshwj xeeb thiab tso cai rau kev lag luam khoom siv roob tshiab hauv kev lag luam khoom siv plastik. Cov kev nruab nrab roob tshiab muaj mechanical recycling, uas nylon khoom roob tshiab tau txiav, saib xyuas, chaw, hlaws, thiab roob tshiab rau hauv pellet; thiab chemical recycling, uas dismantles cov khoom roob tshiab mus rau monomers kom roob tshiab rau hauv resin zoo li tshiab. Khoom roob tshiab los ntawm kev lag luam, zoo li sprues thiab runners los ntawm kev ntxig molding, muab thawj qhov chaw zoo thiab tshaib rau cov khoom roob tshiab zoo. Cov chaw siv los ntawm neeg siv khoom roob tshiab tsis meej dua, suav nrog cov kab ntsa, roj hmab, thiab cov khoom roob tshiab los ntawm kev lag luam tshwj xeeb, uas xav tau kev txiav txim siab thiab kev saib xyuas zoo dua. Qhov teeb meem tshaj plaws nrog polyamide roob tshiab mekanik yog qhov kev hloov pauv ntawm molecular weight thaum muaj ntau dua ib zaug hluav taws xob, uas tuaj yeem cuam tshuam intrinsic viscosity thiab, raws li ntawd, qee yam siv khoom zoo li kev tiv thaiv thiab kev nyuaj siab. Txhawm rau txwv qhov no, cov neeg tsim khoom feem ntau ntxiv chain extenders lossis stabilizers thaum roob tshiab. Ntawm qab no, kev tswj xyuas kev zoo ib yam ntawm li cas thiab siv khoom tuaj yeem nyuaj vim tias muaj kev puas tsuaj. Txhawm tias muaj tej teeb meem no, polyamide roob tshiab tau pom tseeb tshaj plaws hauv cov khoom siv tshwj xeeb tsis yog hauv automotive, electrical connectors, thiab lwm yam khoom siv neeg uas xav tau kev ua zoo tab sis tsis tsum tau zoo li tshiab. Siv polyamide roob tshiab tuaj yeem txo carbon footprint thiab kev siv hluav taws xob ntau dua li tsim khoom tshiab, yog li nws yog qhov leej twg zoo dua rau cov neeg tsim khoom uas xav tshaj tshua rau kev nyab xeeb.
