PVC board kuj tau siv dav hauv lub neej txhua hnub. Niaj hnub no, Qingdao Sainuo polyethylene siv quav ciab chaw tsim tshuaj paus coj koj los paub txog qee yam teeb meem ntawm PVC board.

1. Lub longitudinal thickness sib txawv ntawm PVC lub rooj tsavxwm yog loj
(1) Qhov ntsuas kub ntawm lub thoob yog tsis ruaj khov, uas ua rau lub melt flow rate tsis ruaj khov. Qhov kub ntawm lub thoob yuav tsum tau kho kom stabilize nws.
(2) Qhov tsis ruaj khov ntawm cov ntsia hlau ceev ua rau qhov tsis ruaj khov ntawm extrusion kom muaj nuj nqis. Cov txheej txheem tsis ntawm extruder yuav tsum tau hloov kho kom ua rau extrusion ruaj khov.
(3) Kev sib hloov ceev ntawm peb lub calender tsis ruaj khov, yog li qhov kev sib hloov ceev ntawm peb lub calender yuav tsum tau kho.
(4) Lub traction ceev tsis ruaj khov, ceev thiab qeeb. Lub traction ceev yuav tsum tau kho kom nws khiav smoothly.
2. Tsis sib xws transverse thickness ntawm PVC board
(1) Cov pwm tsim tsis tsim nyog thiab cov ntaub ntawv hla ntu ntu tsis sib xws, yog li cov pwm yuav tsum tau hloov kho kom lub cev tuag tsis zoo.
(2) Kev hloov kho qhov sib txawv ntawm daim di ncauj tuag yog qhov tsis tsim nyog thiab tsis sib xws. Qhov sib txawv ntawm ob sab yuav tsum me ntsis me dua qhov nruab nrab ntawm ob sab.
(3) Qhov sib txawv ntawm peb cov menyuam sib txawv ntawm peb lub calender yog loj, yog li qhov sib txawv ntawm peb lub rollers yuav tsum zoo ib yam.
(4) Qhov siab xaiv thiab kev ua haujlwm ntawm peb cov menyuam tsis tsim nyog. Qhov nruab nrab qhov siab ntawm yob nto yuav tsum tau hloov kom tsim nyog.
3. Qhov saum npoo ntawm PVC board yog ntxhib thiab lusterless
(1) Peb qhov chaw ua haujlwm yog ntxhib lossis muaj cov khoom nplaum. Peb yob ua hauj lwm nto yuav tsum tau muab ntxuav thiab polished kom cov nto ua tau raws li qhov yuav tsum tau du.
(2) Cov menyuam kub ntawm calender yog qis, yog li qhov kub ntawm peb lub rollers yuav tsum tau nce kom zoo.
(3) Yog tias daim di ncauj tuag tsis du, daim di ncauj tuag yuav tsum tau ntxuav.
(4) Yog tias lub lim tau tawg lawm, yuav tsum tau hloov lub lim tshiab.
4. Muaj cov kab hloov pauv ntawm qhov chaw ntawm lub phaj
(1) Kev sib xyaw tsis sib xws ntawm cov khoom ua rau muaj qhov hloov pauv ntawm extrusion kom muaj nuj nqis. Txhawm rau ua kom cov khoom siv plasticized zoo thiab cov extrusion kom muaj nuj nqis tsis sib xws, cov khoom sib xyaw yuav tsum tau hloov thiab cov txheej txheem ntawm extruder yuav tsum tau kho.
(2) Lub chim kub hloov pauv tau zoo heev. Tshawb xyuas thiab kho lub chim tswj qhov system kom paub meej qhov tseeb ntawm qhov ntsuas kub.
(3) Kev sib hloov ceev ntawm peb lub rollers tsis ruaj khov lossis cov menyuam nto yog khawb. Qhov ceev ntawm peb lub rollers yuav tsum tau kho kom nws khiav zoo; Hloov cov menyuam raug mob lossis kho cov menyuam nto.
(4) Traction ceev tsis ruaj khov lossis traction roller siab tsis txaus. Lub traction ceev thiab qhov nro ntawm traction roller yuav tsum tau kho kom lub phaj traction ruaj khov.
5. Cov qauv ntev ntawm lub phaj
(1) Qhov sib txawv qhov qhib ntawm daim di ncauj yog me heev. Nws yuav tsum tau nce kom tsim nyog. Qhov qhib ntawm daim di ncauj yog feem ntau sib npaug los yog me ntsis tsawg tshaj li cov thickness ntawm cov ntawv hlau, uas yog nthuav tom qab extrusion thiab stretched mus rau lub thickness yuav tsum tau.
(2) Lub extrusion kub yog tsawg thiab yaj plasticization tsis zoo. Qhov kub ntawm lub fuselage thiab lub qhov ntswg yuav tsum tau nce kom tsim nyog.
(3) Lub towing ceev yog ceev heev. Nws yuav tsum tau qeeb kom tsim nyog. Lub rub ceev yuav tsum yog me ntsis ceev tshaj qhov extrusion ceev.
6. Warpage
(1) Calender roller kub tswj yog tsis tsim nyog, tshwj xeeb tshaj yog nyob rau hauv nruab nrab thiab qis rau cov menyuam kub yog tsawg heev. Cov menyuam kub yuav tsum tau tswj nyob rau hauv ib tug haum ntau yam.
(2) Qhov chaw sib cuag ntawm ob qhov kawg ntawm lub phaj thiab cov cua yog loj heev, qhov cua txias ceev yog ceev heev, thiab qhov cua txias ceev ntawm qhov nyias nyias ntawm lub phaj kuj tseem ceev. Thaum tsim, lub phaj khoov mus rau thawj qhov chaw txias, ua rau muaj kev ntxhov siab sab hauv. Txhawm rau txo qhov kev ntxhov siab sab hauv ntawm kev tsim, nws yuav tsum tau txias kom sib npaug li sai tau los txo cov cua ntsawj ntshab.
7. Npuas
(1) Cov khoom siv raw yog ntub thiab cov dej noo ntau tshaj tus qauv. Cov ntaub ntawv yuav tsum khaws cia tsis muaj noo noo.
(2) Qhov kub ntawm lub fuselage thiab qhov ntswg yog siab dhau, ua rau cov khoom decomposition. Qhov kub ua haujlwm yuav tsum raug txo kom tsim nyog.
8. Cov kab txaij dub lossis cov xim tsis zoo thiab cov pob zeb ntawm qhov chaw
(1) Lub taub hau kub yog siab dhau lawm thiab cov khoom yog overheated thiab decomposed. Lub taub hau kub yuav tsum tau txo kom zoo.
(2) Muaj lub kaum sab xis tuag nyob rau hauv lub taub hau, thiab cov khoom stagnant yog decomposed. Lub tshuab taub hau yuav tsum tau ntxuav kom tshem tawm lub kaum sab xis.
(3) Muaj impurities thaiv nyob rau hauv lub taub hau, ua rau lub decomposition ntawm stagnant khoom. Lub taub hau tshuab yuav tsum tau ntxuav kom tshem tawm impurities.
(4) Muaj precipitates nyob rau saum npoo ntawm peb lub calender. Cov menyuam nto yuav tsum tau ntxuav kom tshem tawm cov volatiles.
9. Qhov chaw ntawm qhov chaw
(1) Qhov kub ntawm qhov qis qis ntawm peb lub calender yog siab dhau, thiab lub phaj adheres rau saum npoo ntawm cov menyuam. Qhov kub ntawm qis yob yuav tsum tau txo kom zoo.
(2) Lub precipitates ntawm cov kua additives nyob rau saum npoo ntawm peb lub calender ua rau daim ntawv adhere rau saum npoo ntawm cov menyuam, yog li cov menyuam nto yuav tsum tau ntxuav.
10. Qhov chaw txias ntawm qhov chaw
(1) Cov menyuam kub ntawm peb lub calender yog qis heev. Cov menyuam kub yuav tsum tau nce kom tsim nyog.
(2) Muaj wax precipitates nyob rau saum npoo ntawm peb lub calender. Lub yob nto yuav tsum tau ntxuav.
