Dab Tsi Yog Qhov Ntoo Ntawm Ntoo-Yas Ntau Lawm

Tam sim no nrog kev txhim kho ntawm kev sib raug zoo, neeg paub txog kev tiv thaiv ib puag ncig muaj zog tuaj yeem muaj zog. Qhov kho kom zoo nkauj ntawm lub tsev yog tam sim no ua los ntawm kev tiv thaiv ib puag ncig tshiab. Tom ntej no, Xiaobian yuav qhia rau koj txog cov txheej txheem ntoo-yas ntau lawm.

Ntoo ntoo-yas yog ib yam tshiab ntawm cov hluav taws xob tiv thaiv ntawm ib puag ncig ntawm huab cua. Nws yog tsim los ntawm cov khoom siv xws li polyethylene, polypropylene, acrylonitrile / butyrene / styrene copolymer, polyvinyl chloride thiab pov tseg ntoo, sawdust, ntoo twigs, additives.

Cov ntoo ntawm cov ntoo tshauv tau pib nce hauv Tebchaws Meskas thiab Canada hauv xyoo 1990. Vim nws txoj hauv kev zoo siv thiab kev tiv thaiv ib puag ncig, cov ntoo ntawm ntoo-yas tsim tau sai hauv lub ntiaj teb. Nyob rau xyoo 2002, cov khoom siv hluav taws xob ntoo hauv North America thiab Europe tau siab tshaj 680,000 tons. Raws li txoj kev tshawb fawb ntawm Principia Partners Consulting Company hauv Teb Chaws Asmeskas, qhov kev lag luam ntoo wood thoob ntiaj teb yuav tshaj $ 1.4 billion los ntawm 2007, thiab yuav ua kom muaj kev loj hlob zog ntawm xyoo 2010. Qhov loj tshaj daim ntawv thov yog extrusion ntawm cov khoom tsim vaj tse, thiab muaj yuav ntau cov khoom ntoo-yas khoom.

Muaj ntau txoj hauv kev ua cov ntoo ntawm yas ntoo los ntawm kev sib txuas nrog ntoo nrog plastics (thermoplasticity thiab thermosetting), thiab lawv cov txhooj sib txawv. Thaum siv cov thermosetting reagin, cov khoom siv ntoo txeem thiab cov kua txig ntawm ib hom qauv feem ntau sib npaug sib npaug ntawm qhov chaw sov thiab siab. Tom qab ntawd, raws li cov khoom ntawm pob zeb thiab cov kev cai ntawm cov khoom sib xyaw los yog lawv cov khoom, cov khoom raug kho los ntawm tej lub siab thiab qhov kub, uas pib muaj cross-linking polymerization, thiab tom qab hloov kho tom qab.

Thaum siv cov thermoplastics los yog resins, ntoo (fibers, hmoov, ib qho, etc.) feem ntau tov nrog plastics thiab ua cov khoom pab nyob rau hauv chav tsev kub, ces qhov sib tov yog rhuab mus rau high kub kom qhuav lub plastics thiab tag nrho sib tov nrog ntoo. Tom qab ntawd ntws ntoo sib tov yog tsim hauv siab (feem ntau los ntawm extrusion, txhaj, kub nias, thiab lwm yam) thiab tom qab txias thiab solidified kom tau ntoo-yas. Cov khoom ua ke.
