Dab tsi yog qhov txawv ntawm PERT yeeb nkab thiab PE-RT yeeb nkab?
PE-RT cov yeeb nkab, uas yog cov yeeb yaj kiab tiv thaiv tshav kub-polyethylene, yog cov ntawv luv luv ntawm polythene ntawm tsa kub tsis kam yeeb nkab. Nws yog ib hom ntawm cov tsis hla hauv polyethylene yeeb nkab uas tuaj yeem siv tau rau dej kub. Qee tus neeg kuj tseem hais txog nws qhov kev tsis sib xws, thiab hu nws" (PE-RT) Yeeb) yeeb nkab feem ntau hu ua PE-RT pem teb cua sov yeeb nkab, uas feem ntau siv rau hauv kev ua lag luam. Nws yog ib hom nruab nrab ntom polyethylene uas ua los ntawm cov qauv tshwj xeeb qauv tsim thiab sib txawv. Nws siv cov txheej txheem ethylene thiab octene copolymerization kom tau cov qauv tshwj xeeb molecular los ntawm kev tswj hwm tus lej thiab kev faib tawm ntawm cov saw sab nraud, txhawm rau txhim kho cov tshav kub tsis kam ntawm PE yeeb.
Qhov sib txawv ntawm PERT cov yeeb nkab thiab PE-RT cov yeeb nkab yog qhov sib txawv ntawm cov khoom siv raw, cov txheej txheem ntau lawm thiab hom kev sib txuas: 1. Cov khoom siv PERT cov yeeb nkab: cov khoom siv ntawm PERT cov yeeb nkab yog tshuaj lom neeg sib txuas polyethylene. PE-RT yeeb nkab: cov khoom siv raw ntawm PE-RT yeeb nkab yog cov tshav kub-resistant polyethylene. 2. Kev ua cov txheej txheem PERT yeeb nkab cov khoom siv: cov khoom siv raw ntawm PERT cov yeeb nkab tsis kam nrog kub. Thaum lub sij hawm tsim tawm, cov tshuaj lom neeg cov tshuaj tiv thaiv ntawm polyethylene cov khoom siv raw tau paub los ntawm kev tswj qhov ntsuas kub, siab, catalyst (tus neeg sawv cev sib txuas) thiab cov sijhawm tshuaj tiv thaiv (nrawm) los ntawm cov cuab yeej tshwj xeeb, kom cov kab tawm ntawm polyethylene ua lub network qauv. Rt-pe yog ib hom khoom siv tshwj xeeb cov khoom siv rau rt-pe extrusion, uas yog hom khoom kub-resistant kub. 3. Kev sib txuas hom PERT yeeb nkab: PERT yeeb nkab txuas nrog los ntawm hluav taws xob vuam. PE-RT kav dej: PE-RT kav dej txuas nrog los ntawm kub yaj.
