Qhov txawv ntawm WPC Pem Teb Thiab PVC Pem Teb

Cov khoom siv ntoo-yas khoom yog ib yam tshiab ntawm cov khoom sib txuam uas zoo nkauj nyob hauv xyoo tas los hauv tsev thiab txawv teb chaws. Nws yog hais txog kev siv cov polyethylene, polypropylene thiab polyvinyl chloride los hloov cov khoom siv li niaj zaus, thiab sib tov nrog ntau tshaj 50% cov hmoov nplej, kua txiv hmab txiv ntoo, cov quav cab thiab lwm cov khoom pov tseg rau cov ntoo tshiab, uas yog tsim los ntawm extrusion , molding, kev txhaj tshuaj molding thiab lwm cov txheej txheem yas ua. Feem ntau siv los tsim cov khoom siv hauv tsev, rooj tog zaum, kev lag luam thiab lwm yam lag luam. Daim nplaum ntawm cov ntoo uas muaj hlau nplaum yog txheej txheem kub txheej txheem uas muab sib tov ua ke nrog cov hmoov thiab cov hmoov ntoo ua ib feem.

ntsiab nta

Ntoo yas yas yog ua raws li high-density polyethylene (HDPE) thiab ntoo fibres, uas txiav txim xyuas lawv cov khoom ntawm cov khoom siv thiab ntoo.

1) Cov ntoo ntawm cov ntoo uas muaj kev xyuam xim muaj plastics thiab fibres, yog li ntawd lawv muaj txoj haujlwm zoo li ntoo.

Nws tuaj yeem pom, nailed thiab npaj. Nws tuaj yeem nrog cov khoom siv ntoo. Cov ntsia thawv tuav yog obviously superior rau lwm cov khoom siv hluavtaws. Mechanical zog yog superior khoom ntoo. Lub nailing quab yuam yog feem ntau peb zaug ntawm ntoo thiab tsib zaug ntawm particleboard.

2) Cov ntoo ntawm cov ntoo uas muaj lub zog zoo thiab cov ntsiab lus yas yog cov khoob zoo zoo. Tsis tas li ntawd xwb, vim yog lub cev ntawm cov fibers thiab tag nrho sib xyaw nrog plastics, nws muaj tib lub cev thiab cov khoom sib xws li hardwood, xws li compression thiab bending ua hauj, thiab nws cov stability yog zoo dua li cov khoom ntoo zoo tib yam. Kev ntes hardness yog siab, feem ntau 2 - 5 zaug ntawm ntoo.

3) Nws muaj cov dej tsis haum thiab kev xeb tuaj yeem ua haujlwm. Muab piv rau ntoo, yas-yas khoom thiab khoom nrog lub neej ntev kev muaj peev xwm tiv taus muaj zog acid thiab alkali, dej tsis kam thiab corrosion tsis kam. Lawv tsis nteg cov kab mob thiab tsis yoojyim yuav npauj-noj thiab loj hlob zoo nkauj. Kev pab lub neej ntev, mus txog 50 xyoo.

4) Kho zoo tshaj plaws ntawm cov khoom uas yuav hloov tau los ntawm cov additives xws li polymerization, foaming, tua thiab kev hloov kho.

Hloov qhov ceev thiab lub zog ntawm cov khoom ntoo-yas kuj muaj peev xwm ua tau raws li kev tshwj xeeb ntawm kev laus, kev tiv thaiv, hluav taws kub nyhiab thiab lwm yam.

5) Nws muaj qhov ruaj ntseg ntawm ultraviolet lub teeb thiab zoo xim.

6) Qhov loj tshaj plaws yog kom tig mus pov rau hauv cov khoom muaj nqis, thiab rov tuaj yeem siv tau 100% rov qab. Nws tuaj yeem ua rau "tsis muaj kuab paug"

Nws yog ib qho tiag tiag ntsuab environmental tiv thaiv khoom.

7) Cov ntaub ntawv tseem ceeb rau cov khoom siv ntoo-yas yog cov ntom tshuaj polyethylene (HDPE) lossis polypropylene (PP). Ntoo fibers tuaj yeem ua hmoov nplej, txhuv bran los yog ntoo fibers. Ntxiv rau, ib qho me me ntawm cov additives thiab lwm yam khoom siv yuav tsum tau.

8) Nws tuaj yeem ua tau rau txhua tus qauv thiab loj raws li qhov xav tau.

PVC:

Polyvinyl chloride (PVC) yog ib qho pib ntawm cov chloride chloride monomer (VCM) xws li cov tshuaj peroxide thiab azo, los yog lub polymer synthesized los ntawm dawb radical polymerization nyob rau hauv qhov kev txiav txim ntawm lub teeb thiab cua sov. Lub homopolymer ntawm yas chloride thiab copolymer ntawm yas chloride yog collectively hu ua yas chloride cob.

Qhov ceev ntawm cov hluav taws xob polyethylene chloride yog 1.4 g / cm3. Qhov ceev ntawm polyethylene chloride diluted qhov chaw nrog cov khoom yas thiab cov roj paug feem ntau yog 1.4 g / cm3.

1.15-2.00g / cm3

Nyuaj polyethylene chloride tau zoo tensile, dabtsi yog khoov, compressive thiab tej yam kuj, thiab yuav siv tau raws li cov ntaub ntawv structural ib leeg.

Lub softness, elongation ntawm so thiab txias tsis kam ntawm polyvinyl chloride yuav nce, tab sis lub brittleness, hardness thiab tensile lub zog yuav txo.

Polyvinyl chloride muaj hluav taws xob rwb thaiv tsev zoo, siv tau raws li khoom tsawg zaus rwb thaiv tsev, thiab nws txoj kev ruaj ntseg chemical kuj zoo. Vim cov neeg txom nyem thermal stability ntawm polyethylene chloride, ntev lub caij cua sov yuav ua rau decomposition, tso HCL roj, ua polyethylene chloride dilute heev, vim li ntawd nws daim ntawv thov yog nqaim, qhov kub thiab txias yog feem ntau ntawm - 15 ~ 55 degrees.

Txawv: 1. Cov khoom sib txawv

2. Kev tiv thaiv ib puag ncig kuj txawv dua.

3. PVC yog yas thiab WPC yog ntoo-yas.
