Kev Txhim Kho Kev Cia Siab ntawm WPC

1) Cov ntaub ntawv zoo raw khoom thiab cov qauv kev tshawb fawb Cov ntaub ntawv tseem ceeb ntawm lub qhov rooj ntoo-yas yog PVC resin thiab cov hmoov ntoo zoo. PVC cob yog ua los ntawm kev kho mob-qib domestic nto moo hom khoom. Kev ziab, txheej txheej kho, kom ntseeg tau tias cov khoom tiav tiav ntawm cov khoom siv raw. Cov qauv txheej txheem ntawm lub qhov rooj ntoo-yas yog nruab nrog ib qho kev faib ua feem ntawm cov khoom siv, nrog rau cov stabilizers, foaming agents, modifiers, thiab lwm yam, thiab ntau yam khoom sib xyaw ua ke hauv cov proportions nruj kom zoo xyuas cov khoom zoo ntawm foamed board.

2) Cov khoom siv ntau lawm Cov khoom siv ntau lawm yog tuaj ntawm txawv teb chaws los ntawm kev sib xyaw ua ke mus rau qhov extrusion system, uas yog nyob rau theem thoob ntiaj teb thiab muaj qib siab ntawm automation. khoom stability. Vim tias qhov kev xav tau siab rau cov khoom siv ua npuas ncauj extrusion hauv kev tsim cov ntoo-yas ua npuas ncauj qhov rooj, siv lub siab torque twin-screw extruder, thiab cov ntsia hlau, ntsia hlau chim thiab lwm yam khoom raug hloov kho kom haum rau lignin sab hauv thiab sab nrauv. crusting thiab Foam tusyees kom tsis txhob tshwm sim ntawm ntoo hmoov charring thiab lwm yam phenomena.

3) Cov thev naus laus zis thev naus laus zis siv cov thev naus laus zis thev naus laus zis los siv cov txheej txheem thermal hloov pauv ntau yam duab ntawm daim ntawv extruded, kom cov khoom muaj ntau hom ntoo nplej thiab xim. Raws li cov khoom nrov hauv kev ua lag luam, peb tsim cov walnut dub, ivory Dawb, siv quav ciab ntoo thiab lwm yam tiav muaj rau cov neeg siv khoom xaiv los ntawm, thiab ntau tshaj 50 lub qhov rooj tsim tsim los ua kom tau raws li cov kev xav tau ntawm cov neeg siv khoom niaj hnub no.

4) Cov ntaub ntawv raw siv rau lub qhov rooj ntsuab thiab ib puag ncig tus phooj ywg WPC yog ib zaug molding nyob rau hauv qhov kub thiab txias, kev kub siab thiab lub tshuab nqus tsev, cov khoom siv tsis muaj formaldehyde, thiab cov txheej txheem thib ob txais cov thev naus laus zis thev naus laus zis, tsis muaj xim, thiab tsis muaj tshuaj lom lossis tsis zoo thaum tsim khoom thiab siv. Gas thiab tsw tso tawm, ib tug tib neeg-phooj ywg cov khoom uas ua tau raws li ib puag ncig cov qauv rau niaj hnub interiors.

5) Waterproof, noo noo-pov thawj, tiv thaiv corrosion, mildew-pov thawj, npauj-pov thawj thiab tsis-deformable WPC cov khoom muaj ob tus yam ntxwv ntawm ntoo thiab yas, yog li WPC teeb qhov rooj yog tshwj xeeb tshaj yog haum rau loj kub sib txawv, av noo thiab tsis zoo. qhov cua tsuas yog rau lub qhov rooj sab hauv. qhov chaw, xws li damp chav da dej, anti-corrosion, mildew-proof, npauj-pov thawj chav cia, thiab lwm yam.

6) Cov qauv tsim nyog thiab lub zog siab Qhov tshwj xeeb kab kab noj hniav qauv tsim kom paub meej cov qauv sab hauv ntawm cov khoom siv ntoo-yas ua npuas ncauj, ua ke nrog cov qauv tsim qauv tsim nyog thiab tsim nyog cov txheej txheem, kom ntseeg tau tias lub zog ntawm cov khoom.

7) Kev teeb tsa sai, txuag lub sijhawm thiab kev siv zog hauv kev teeb tsa Lub qhov rooj yas ntoo txais cov qauv kev teeb tsa ceev tuaj ntawm lub teb chaws Yelemees, thiab kev teeb tsa ntawm lub qhov rooj npog yog qhov yooj yim heev.

8) Cov rwb thaiv tsev zoo thiab lub suab rwb thaiv tsev Cov ntaub ntawv siv rau hauv cov ntoo-yas teeb qhov rooj muaj cov yam ntxwv zoo thiab zoo thiab cov qauv tsim tshwj xeeb hauv kab kab noj hniav, uas ua kom nws cov thermal conductivity qis dua li cov ntaub ntawv yas zoo tib yam thiab txo cov suab nrov. kev ua tau zoo dua. Tom qab kev sim, lub tshav kub hloov coefficient ntawm cov khoom no yog 1W / m2.k, thiab thermal rwb thaiv tsev kev ua tau zoo mus txog qib thawj GB / T16729-1997; Lub suab rwb thaiv tsev kev ua tau zoo yog qib 6, nrog cov rwb thaiv tsev zoo thiab lub suab rwb thaiv tsev 9) Cov nplaim hluav taws zoo ua haujlwm zoo WPC Lub qhov rooj ntawm cov khaub ncaws tsis txhawb kev sib tsoo thaum lub nplaim taws qhib, thiab nws yuav cia li tawm mus tom qab tseem ciaj sia. . Tom qab kev sim, cov pa ntsuas ntawm Longqiao WPC teeb qhov rooj yog 48, thiab nws cov qib hluav taws kub yog B1. Qhov kev ua tau zoo ntawm Longqiao WPC teeb qhov rooj yuav ua kom muaj kev nyab xeeb ntawm hluav taws hauv tsev zoo heev.

Cov khoom siv hauv tsev hauv tsev tau dhau los ntawm ob tiam neeg: thawj tiam yog ntoo thiab ntoo, thiab tiam thib ob yog cov khoom siv ntoo uas sawv cev los ntawm plywood, fiberboard, particleboard, thiab ntoo pulp. Nyob rau hauv 2003, kuv lub teb chaws cov ntoo-raws li vaj huam sib luag ntau lawm ranked thawj nyob rau hauv lub ntiaj teb no. Lub cim thib peb yog cov khoom siv ntoo-yas, uas tau ci ntsa iab hauv kev ua lag luam. Cov khoom siv ntoo-yas muaj ob qho tib si zoo ntawm cov yas thiab ntoo, thiab muaj qhov zoo tshaj plaws hauv cov ntaub ntawv vaj huam sib luag. Tam sim no, kev lag luam hauv tsev WPC muaj peev xwm loj heev. Txawm hais tias txhua xyoo cov khoom tsim tawm ntawm WPC hauv ntiaj teb tsuas yog ob peb lab tons, txij li xyoo 1998, Tebchaws Europe thiab Tebchaws Meskas thiab lwm lub tebchaws tau nce ntawm tus nqi ntawm 65 feem pua ​​​​txhua xyoo. Ntawm 10 cov tuam txhab ntoo-yas hauv tsev, 7 yog cov tuam txhab txawv teb chaws, thiab tag nrho cov khoom raug xa tawm.

ChemChina lub chaw soj ntsuam cov khoom tau nruj me ntsis soj ntsuam kev ua tau zoo thiab kev tiv thaiv ib puag ncig ntawm cov khoom kom ntseeg tau tias cov cai thiab kev nyiam ntawm cov neeg siv khoom tsis raug mob.

Cov khoom siv zoo, tuaj yeem saws, npaj, nailed thiab lwm yam khoom siv xws li ntoo, nrog cov tawv tawv, tawv, ruaj, hnav-tiv taus; tom qab foaming, ib tug loj tus naj npawb ntawm uniform thiab li niaj zaus hlwb raug tsim, uas yuav txuag tau tus nqi ntawm cov khoom. Cov kev sim qhia tau hais tias, piv nrog cov hmoov nplej tsis muaj PVC / ntoo hmoov sib xyaw, qhov ntom ntom tuaj yeem raug txo los ntawm 50 feem pua ​​tom qab extrusion foaming thiab tuaj yeem ncav cuag 0.6g/-1.0g/cm3. Lub cev tsis tu ncua thiab cov qauv ntawm tes tom qab foaming tuaj yeem passivated Lub elongation ntawm kev tawg ntawm qhov tawg tuaj yeem txhim kho tau zoo. Nws kuj yog ib qho khoom siv rau ib puag ncig. Cov khoom siv raw yog pheej yig, muaj ntau, thiab rov ua dua tshiab, uas tuaj yeem txo cov pa phem ib puag ncig thiab tiv thaiv hav zoov cov peev txheej.
