Yas yog cov khoom siv los ua raws li cov polymers sib txawv. Yog li ntawd, ntawm kev ua lag luam koj tuaj yeem nrhiav cov khoom sib xyaw nrog cov nplaum sib txawv. Muaj ob qho tib si tseev tsim ntiaj teb thiab tshwj xeeb ntawm hom nplaum. Ntau txoj kev tuaj yeem siv tau thaum koom nrog qhov chaw yas.
Xaiv cov kua nplaum zoo
Thaum xaiv cov nplaum, nco ntsoov tias kev siv cov thauv yas txawv teb chaws yog qhov tsis xav tau. Tsis tas li ntawd, ntau cov yas muaj ntau cov tshuaj tiv thaiv uas muaj qhov tsis zoo ntawm lub zog. Qee zaum cov txheej txheem txhaj tshuaj siv hauv kev tsim cov yas. Raws li cov kev kho mob no, nplaim yog du heev. Nws xav tau kev npaj zoo ua ntej ci.
Tshawb xyuas cov cim cim uas feem ntau siv rau sab hauv ntawm cov yas. Piv txwv li, PUR yog polyurethane, thiab PP yog polypropylene, ABS, PVC yog phenol thiab fiberglass. Nws feem ntau yog siv rau sab hauv qhov ntawm. Ntawm cov ntawv nplaum uas nrov tshaj plaws haum rau ntau hom plastics yog: Lub sij hawm zoo, Muaj Plast, UNU, Welcon constraction, AKEIX. Kev tsim qauv siv thoob ntiaj teb tuaj yeem siv tau yog tias koj tsis siv ntau yam yas. Tab sis rau gluing polyurethane, ntaub hlua kaus, fiberglass thiab phenol, nws yog qhov zoo dua los siv ob-txheej txheem ntawm cov nplaum, piv txwv li, Welcon constraction. Cov nplaum tsim nyog rau kev siv sab hauv tsev thiab sab nraum zoov.
Xaiv txoj kev raug
Cov txheej txheem cua sov yuav pab txhawm rau txhim kho qhov zoo ntawm kev sib khi ntawm qee hom plastics. Nws yog qhov tsim nyog rau thermosetting polymers lossis polyurethanes. Qhov kev sib txuas ntawm cov khoom muag muag yuav ua kom lub zog adhesion zoo. Qee zaum cov kev daws teeb meem ntawm ntau cov polymers siv. Lawv pab ua kom haum xeeb kev nyiam ntawm txoj kab kua nplaum. Kev sib raug zoo tshaj plaws ntawm cov tawv polyurethane thiab polypropylene tuaj yeem ua tiav nrog epoxy nplaum.
Rau txoj kev sib txuas zoo ntawm ob lub ntsiab yas, lawv yuav tsum ceev cia hauv qab lub sijhawm. Qhov txheej txheem txhawb zog kuj tseem siv tau rau kev ua kom ruaj khov. Piv txwv li, txheej txheej ntawm cov xim hlau yog siv rau cov yas ua kom sov - cov hlau cam los yog cov ntawv ntim steel, uas yaj hauv cov kuab tshuaj organic los yog muab sib xyaw nrog cov yas ua los ntawm cua kub. Xaiv ib qho kuab tshuaj raws li hom yas. Piv txwv, toluene yog qhov haum rau polystyrene.
Ntawm kev muag koj tuaj yeem nrhiav cov ntaub nplaum tshwj xeeb uas siv tshwj xeeb txawm rau qhov tsis npaj saum npoo. Muab ob npaug rau daim nplaum ob txoj xaim tshwj xeeb uas tsim tshwj xeeb rau plastics yuav pab tau sai sai ua kom daim nplaum yas. Cov ntaub nplaum zoo li no tso cai rau koj txuas tsis yog thaj chaw zoo nkauj xwb, tabsis tseem yuav siv yas thiab iav, hlau, ntoo.
