Cov ntsiab lus ntau lawm:
Cov yeeb nkab sib xyaw ua los ntawm hlau hlau uas muaj zog yog cov yeeb nkab yas sib xyaw ua los ntawm hlau hlau tshiab uas zoo dua qub. Cov yeeb nkab hom no kuj hu ua SRTP yeeb nkab. Cov yeeb nkab hom tshiab no yog ua los ntawm cov hlau hlau uas muaj zog heev thiab cov thermoplastic polyethylene ua cov khoom siv raw, cov hlau hlau uas muaj zog ua los ntawm cov yeeb nkab yas polyethylene, cov polyethylene siab ceev (HDPE) asmatrix, nrog kev ua tau zoo ntawm HDPE hloov kho cov roj hmab sib txuas ua ke yuav ua rau cov hlau ncej nrog cov txheej sab hauv thiab sab nraud ntawm cov polyethylene siab ceev ze ua ke, yog li nws muaj cov txiaj ntsig zoo heev. Cov yeeb nkab sib xyaw kov yeej qhov tsis zoo ntawm ob qho tib si hlau thiab yas, thaum khaws cov txiaj ntsig ntawm ob qho tib si, vim tias cov hlau muaj zog siab tau qhwv rau hauv cov thermoplastic tas mus li.
Cov yeeb nkab hlau uas tau kho dua tshiab, siv cov khoom siv zoo thiab cov thev naus laus zis siab heev, kom nws muaj kev ua haujlwm siab dua. Tib lub sijhawm, cov yeeb nkab sib xyaw muaj kev ywj pheej zoo heev, tsim nyog rau kev xa dej mus deb thiab cov kav dej roj. Cov yeeb nkab polyethylene electrofuse siv rau cov yeeb nkab polyethylene sib xyaw ua ke uas tau kho dua tshiab. Thaum txuas, lub cev cua sov sab hauv ntawm cov yeeb nkab siv los yaj cov yas sab nraud ntawm cov yeeb nkab thiab cov yas sab hauv ntawm cov yeeb nkab, kom cov yeeb nkab thiab cov yeeb nkab sib txuas ua ke tau zoo.
