1. Extruder kub
Thaum tshuab tsis tshua muaj siab polyethylene (LDPE) zaj duab xis, qhov kub ntawm extrusion feem ntau tswj ntawm 160 degree thiab 170 degree, thiab qhov kub ntawm lub tshuab taub hau yuav tsum zoo ib yam. Yog hais tias lub extrusion kub siab dhau lawm, cov resin yog yooj yim decomposed, thiab zaj duab xis yog nkig, tshwj xeeb tshaj yog lub longitudinal tensile lub zog yog ho txo; Yog tias qhov kub thiab txias qis dhau, cov resin yuav tsis zoo plasticized, thiab kev nthuav dav thiab ncab tsis tuaj yeem ua tau zoo. qauv thiab unmelted nuclei (ntses qhov muag).
2. Tus nqi nce nqi
Inflation ratio yog ib qho ntawm kev tswj cov ntsiab lus ntawm cov txheej txheem cua tshuab, uas yog hais txog qhov sib piv ntawm txoj kab uas hla ntawm cov yeeb yaj kiab npuas tom qab kev nce nqi thiab txoj kab uas hla ntawm lub nplhaib tsis muaj zog. Tus nqi nce nqi yog qhov transverse expansion ntau ntawm zaj duab xis. Qhov tseeb, zaj duab xis yog stretched nyob rau hauv lub transverse kev taw qhia. Lub stretching yuav taw qhia cov yas molecules rau ib qho twg, thiab qhov kev nce nqi yuav nce ntxiv, yog li ua rau lub zog transverse ntawm zaj duab xis. Txawm li cas los xij, qhov sib piv yuav tsum tsis txhob loj dhau, txwv tsis pub cov npuas yuav tsis ruaj khov thiab zaj duab xis yuav ua rau wrinkling. Yog li ntawd, tus nqi nce nqi yuav tsum tau ua kom zoo nrog qhov sib piv traction. Feem ntau hais lus, tus nqi nce nqi ntawm cov yeeb yaj kiab uas tsis tshua muaj polyethylene (LDPE) yuav tsum tau tswj ntawm 2.5-3.0.
3. Traction piv
Qhov sib piv yog hais txog qhov sib piv ntawm qhov rub nrawm ntawm zaj duab xis thiab qhov nrawm ntawm lub nplhaib raj. Qhov sib piv yog qhov sib piv ntawm qhov kev taw qhia longitudinal, uas ua rau cov yeeb yaj kiab muaj kev taw qhia zoo nyob rau hauv cov kev taw qhia ntawm kev coj-up. Thaum lub traction ratio nce, lub longitudinal zog kuj yuav nce, thiab lub thickness ntawm cov zaj duab xis yuav ua thinner. Txawm li cas los xij, yog tias qhov sib piv traction loj dhau, lub thickness ntawm zaj duab xis yuav nyuaj rau tswj, thiab cov yeeb yaj kiab kuj tseem raug rub tawm, ua rau cov yeeb yaj kiab tawg. Qhov sib piv ntawm qhov tsawg ntom polyethylene (LDPE) zaj duab xis yog feem ntau tswj ntawm 4-6.
4. Dew point
Lub dew point, tseem hu ua kab Frost, hais txog txoj kab ciam teb uas cov yas hloov pauv los ntawm lub xeev cov dej khov mus rau lub xeev siab elastic. Thaum lub sij hawm ua zaj duab xis tshuab, qhov tsawg ntom polyethylene (LDPE) yog nyob rau hauv lub molten lub xeev thaum extruded los ntawm cov tuag thiab muaj zoo pob tshab. Tom qab tawm hauv qhov tuag, qhov chaw tshuab ntawm cov yeeb yaj kiab npuas yog txias los ntawm lub nplhaib cua txias. Thaum cov cua txias tshuab rau cov yas zaj duab xis npuas tsuas yog extruded los ntawm lub taub hau tuag ntawm ib lub kaum ntse ntse thiab ceev, lub siab kub zaj duab xis npuas thiab cua txias nyob rau hauv kev sib cuag, lub tshav kub ntawm zaj duab xis npuas yuav nqa tawm los ntawm cov cua txias, thiab nws qhov kub thiab txias yuav poob qis qis qis qis qis qis ntawm qhov ntom ntom polyethylene (LDPE), kom nws txias thiab khov thiab ua huab. Ntawm lub tshuab npuas zaj duab xis peb tuaj yeem pom cov kab sib faib ntawm cov pob tshab thiab qhov muag plooj, uas yog qhov dej lwg taw tes (los yog kab te).
Nyob rau hauv cov txheej txheem tshuab tshuab, lub lwg taw tes muaj qee yam cuam tshuam rau kev ua yeeb yaj kiab. Yog hais tias lub dew point yog siab thiab nyob rau saum toj ntawm lub inflated npuas, qhov inflation ntawm cov zaj duab xis yog nqa tawm nyob rau hauv ib tug ua kua lub xeev, lub inflation tsuas yog thins cov zaj duab xis, thiab cov molecules tsis raug mus rau stretch orientation, qhov kev ua tau zoo ntawm lub tshuab cua tshuab. lub sij hawm no yog ze rau ntawm cast film. Ntawm qhov tsis sib xws, yog tias cov dej dew taw tes qis qis, qhov kev nce nqi yog nqa tawm hauv lub xeev ruaj khov. Thaum lub sij hawm no, cov yas yog nyob rau hauv ib tug siab elastic xeev, thiab lub inflation yog zoo li transverse stretching, thiaj li hais tias cov molecules yog oriented, thiaj li hais tias qhov kev ua tau zoo ntawm cua tshuab yog ze rau Orientation zaj duab xis.
