Hollow board yog dav siv vim nws qhov zoo. Cov yas hollow board muaj cov dej noo tsis kam, kev laus tiv thaiv, kev coj tus kheej lub zog, shrinkage, kua muag, siab kub, nplua nuj xim, shockproof, hloov qauv tsim, tsis tas yuav qhib txhaj tshuaj pwm.
Nta ntawm lub tshuab teeb tsa thiab annealing rauv taws kub:
1. Cov kev txhim kho tsis haum, cov plua plav tawm thiab cov yam ntxwv ntawm lub rooj nqus teeb tsa ua kom yooj yim rau kev khiav lag luam.
2. Qhov tshwj xeeb tsim ntawm qhov system txias thiab lub tshuab nqus tsev ntawm lub tshuab teeb ua kom paub meej cov kev kub ceev extrusion chaw.
3. Tshwj xeeb annealing rauv taws tsim, yooj yim los tswj dua li lwm hom ntawm txoj kab extrusion, flatness ntawm lub phaj.
4. Cov huab cua ntim thiab tsis tshua muaj siab ntawm hollow phaj yuav tsum kho thiab yooj yim rau kev khiav lag luam.
5. UV-puag txheej co-extrusion txheej tuaj yeem yog ib leeg lossis ob tog, thiab sab txheej txheej sab nraud yuav tsum muab txhuam lossis txhuam kom huv raws cov qauv.
