Cov laj thawj tseem ceeb vim li cas PVC tau dav siv hauv kev lag luam khoom siv hauv tsev

Cov khoom siv PVC: daim hlau, cov kav dej, cov khau khau, cov khoom ua si, qhov rooj thiab qhov rais, cov hlua khi, cov ntawv sau, thiab lwm yam.

Yog li vim li cas nws thiaj tuaj yeem siv dav hauv cov khoom siv hauv tsev?

Ib qho yog cov khoom tshwj xeeb ntawm PVC (tsis muaj dej nag, hluav taws kub- tiv taus, tiv thaiv- zoo li qub, yooj yim rau kev tsim), thiab lwm yam yog cov yam ntxwv ntawm cov khoom siv qis thiab cov zis siab ntawm PVC. Yog li, vim li cas PVC muaj ob qhov zoo saum toj no? Cia peb pom cov lus teb los ntawm nws cov txheej txheem ntau lawm.

Cov txheej txheem ntau lawm ntawm PVC tsis yog qhov nyuaj. Cov kab ntau lawm feem ntau yog tsim los ntawm lub tshuab dov, lub tshuab luam ntawv, rov qab coater thiab lub tshuab txiav. Cov yeeb yaj kiab ntawm 0.3 hli mus rau 0.7 hli yog tsim nyob rau tib lub sijhawm thiab luam tawm rau sab pem hauv ntej ntawm zaj duab xis los ntawm lub tshuab luam ntawv, thiab lub tsho sab nraub qaum yog txuas rau sab nraub qaum ntawm zaj duab xis los ntawm lub coater rov qab. Tab sis tsis txhob kwv yees cov txheej txheej rov qab no, nws yog ib qho tseem ceeb lav rau siab - kev ua tau zoo ntawm PVC zaj duab xis. Cov txheej sab nraub qaum yog tsim los ntawm cov ntaub ntawv tshwj xeeb thiab yog siab heev -lub zog affinity agent. Nws yog qhov tseeb vim tias cov txheej txheem rov qab no yog PVC zaj duab xis tuaj yeem ua ke nrog MDF lossis lwm cov laug cam, thiab nws yuav tsis raug kaw rau kaum lossis kaum tsib xyoos. Qhov teeb meem loj tshaj plaws ntawm cov veneer zoo tib yam yog tias nws tsis tuaj yeem daws qhov teeb meem ntawm zaj duab xis ntog. Txij li thaum tag nrho cov txheej txheem tsim khoom yog nqa tawm ntawm qhov kub thiab txias (qhov kub ntawm lub tshuab dov mus txog 220 degrees), qhov no ua rau PVC zaj duab xis muaj lub teeb pom kev zoo thiab hluav taws kub tsis kam, ua kom zoo ntawm PVC zaj duab xis. Tau kawg, qhov no yuav tsum tau siv tshuab ntau lawm. Feem ntau, tus nqi ntawm cov khoom siv rau cov kab ntau lawm yog kwv yees li 39 lab cim, sib npaug li 160 lab yuan. Ntawm qhov tod tes, cov txheej txheem ntau lawm ntawm PVC zaj duab xis yog qhov yooj yim heev, thiab cov zis ntawm lub tshuab kuj loj. Yog li ntawd, los ntawm kev pom dav dav, PVC yog qhov tseeb - tawm tswv yim, siab - cov khoom lag luam tawm.
