Cov yeeb nkab qib PP PA14D rau cov kav dej

PP PA14D yog ib hom polypropylene (PP) cob uas tau tsim tshwj xeeb rau kev siv hauv kev tsim cov kav dej. Cov khoom no yog qhov hnyav molecular, random copolymer uas muaj kev tiv thaiv zoo heev rau cov tshuaj thiab kub kub, ua rau nws tsim nyog rau kev siv hauv cov kav dej.

Txhawm rau tsim cov kav dej, thawj kauj ruam yog extrude cov resin rau hauv cov yeeb nkab. Extrusion yog txheej txheem kev tsim khoom uas cuam tshuam nrog cov yas resin yaj thiab tom qab ntawd yuam nws los ntawm kev tuag los tsim cov duab uas xav tau.

Tom ntej no, cov yeeb nkab extruded yog txias thiab txiav mus rau qhov xav tau ntev. Cov yeeb nkab uas tau tshwm sim yog tom qab ntawd npaj siv rau hauv cov kav dej.

PP PA14D muaj kev tiv thaiv zoo rau cov tshuaj xws li tshuaj chlorine, uas feem ntau siv hauv cov dej kho dej. Nws kuj muaj qhov siab melting point, uas ua rau nws haum rau siv hauv cov dej kub. Tsis tas li ntawd, nws muaj kev cuam tshuam zoo thiab muaj peev xwm tiv taus cov kev ntxhov siab thiab kev ntxhov siab cuam tshuam nrog cov kav dej.

Cov kav dej ua los ntawm PP PA14D yog lub teeb yuag, ruaj khov, thiab yooj yim rau nruab. Lawv kuj yog cov tshuaj tiv thaiv corrosion, uas ua rau lawv xaiv zoo heev rau kev siv hauv dej thiab kev faib khoom.

Zuag qhia tag nrho, cov khoom siv yog cov khoom siv txhim khu kev qha thiab siv tau zoo rau kev tsim cov kav dej vim nws cov tshuaj lom neeg zoo heev, kub tsis kam, thiab lub zog siv tshuab.
