Thaum peb tev tawm ntawm daim phaj txhuas, peb yuav pom tias muaj cov cim tsis zoo ntawm kev nplaum nrog nyob ib puag ncig bubbling. Qhov laj thawj rau qhov paib no yog tias cov huab cua nyob ib ncig ntawm lub bubbling tsis tuaj yeem sib zog tawm thiab zawm thaum lub bubbling nyob hauv qhov chaw sib txuas. Hauv nruab nrab ntawm cov vaj huam sib luag, cov huab cua nyias txheej dhau los thaiv tag nrho cov nplaum ntawm lub vaj huam sib luag. Cov noinfusibles tuaj yeem ua rau khoom tsis haum rau cov khoom yas lossis cov yas. Cov ntsiab lus yaj ntawm cov plastics no ntau dua li ntawm polyethylene. Lawv tsis tuaj yeem yaj nyob rau hauv pob thiab raug thaiv ntawm ib sab ntawm daim hlau tsis xeb hlau. Rau qee qhov, nws yuav ua rau extrusion rov qab siab kom nce, kom nws tawg lub lim thiab yog extruded ua ke kom ua bubbling ntawm cov phaj tseem ceeb.
Thaum tsim cov paib nyias nyias, nws yog qhov yuav tsum tau siv qee tus naj npawb ntawm cov hlau tsis xeb hlau rau kev lim. Rau txhuas-yas tub ntxhais daim hlau, qee qhov qhov phaj nrog qee qhov pore loj me dua li phaj tuab tuaj yeem siv los lim, uas yuav tsis ua rau muaj qhov tshwm sim ntawm qhov hnoos qeev, uas feem ntau tuaj yeem daws qhov teeb meem bubbling ntawm txhuas puas vaj huam sib luag.
Qee lub chaw ua haujlwm me me uas tsis muaj kev paub dhau los yuav muaj qhov teeb meem zoo li no, thiab peb lub Hoobkas zoo li Huabond, uas tshwj xeeb hauv kev tsim cov txhuas puas vaj huam sib luag nrog ntau tshaj 20 xyoo ntawm kev nplua nuj ntau lawm yuav tsis ua qhov kev ua qias li no.
