Daim ntawv thov
PP (polypropylene) cov kav dej muaj npe nrov rau lawv qhov tshwj xeeb ruaj khov, uas feem ntau yog vim lawv qhov sib xyaw ua ke ntawm lub teeb yuag, weldability, thiab kev puas tsuaj. Cov kav dej no yog tsim los ntawm cov thermoplastic polymer uas nthuav tawm lub zog zoo thiab muaj zog, ua rau lawv xaiv zoo rau ntau yam kev siv.
Ib qho txiaj ntsig tseem ceeb ntawm cov kav dej PP yog lawv lub teeb yuag, uas tso cai rau kev txhim kho yooj yim thiab tuav. Cov yam ntxwv no, ua ke nrog lawv cov weldability zoo heev, ua rau nws muaj peev xwm tsim cov pob qij txha uas muaj zog, tuaj yeem tiv taus qhov kub thiab txias. Kev puas tsuaj ntawm cov kav dej PP txuas ntxiv txhim kho lawv cov kav ntev, kom ntseeg tau tias lawv tuaj yeem tiv taus qhov hnav thiab tsim kua muag cuam tshuam nrog kev siv tas li thiab raug rau qhov chaw hnyav.
Ntxiv rau lawv cov khoom siv kho tshuab, PP cov kav dej kuj paub txog lawv qhov zoo tshaj plaws thermal thiab hluav taws xob rwb thaiv tsev muaj peev xwm. Qhov no txhais tau hais tias lawv tuaj yeem tiv thaiv kev hloov pauv ntawm tshav kub thiab hluav taws xob, ua rau lawv tsim nyog siv rau hauv cov ntawv thov uas tswj qhov kub thiab txias thiab hluav taws xob rwb thaiv tsev yog qhov tseem ceeb. Kev kub siab txog li 90 ̊C tsis cuam tshuam qhov kev ncaj ncees ntawm cov kav dej PP nyob rau lub sijhawm ntev, thaum lub sijhawm luv luv kub nce mus txog 110 ̊C kuj tau txais txiaj ntsig zoo.
Lwm qhov txiaj ntsig tseem ceeb ntawm cov kav dej PP yog lawv cov tshuaj lom neeg tshwj xeeb. Lawv muaj peev xwm tiv taus aqueous, acidic, thiab cov kev daws teeb meem yooj yim, nrog rau cov ntsev thiab feem ntau cov kuab tshuaj organic. Qhov no ua rau lawv muaj kev xaiv zoo tshaj plaws rau kev siv tshuaj ua cov nroj tsuag, cov chaw kho dej, thiab lwm yam kev siv hauv kev lag luam uas raug rau cov tshuaj hnyav heev.
Thaum nws los koom nrog PP kav, fusion vuam yog txoj kev nyiam. Cov txheej txheem no suav nrog cua sov qhov kawg ntawm cov kav dej kom txog thaum lawv ua molten, ces fusing lawv ua ke los tsim kom muaj zog, seamless sib koom ua ke. Fusion vuam ua kom ntseeg tau tias qhov sib koom ua ke yog ruaj khov raws li cov yeeb nkab nws tus kheej, tsis muaj cov ntsiab lus tsis muaj zog lossis muaj peev xwm xau.
Zuag qhia tag nrho, PP kav yog ib qho kev xaiv ntau yam thiab txhim khu kev qha rau ntau yam kev siv. Lawv lub teeb yuag, ruaj khov, thiab cov khoom siv tshuaj tiv thaiv ua rau lawv muaj kev xaiv zoo rau kev siv hauv kev lag luam, thaum lawv cov thermal thiab hluav taws xob rwb thaiv tsev muaj peev xwm ua rau lawv haum rau siv ntau yam kev siv. Txawm hais tias koj tab tom nrhiav rau cov yeeb nkab uas tuaj yeem tiv taus qhov kub thiab txias, tshuaj hnyav, lossis ob qho tib si, PP cov kav dej yog qhov kev xaiv zoo tshaj plaws uas muaj kev ua tau zoo thiab ua haujlwm ntev.
