Tshav Dav Hlau Nanning: Tshem tawm cov khoom uas tsis lwj, thov sau cov khoom uas lwj
Tshav Dav Hlau Nanning tau tshaj tawm "Cov Cai Tswjfwm thiab Txwv Tsis Pub Siv Yas ntawm Tshav Dav Hlau Nanning" los txhawb kev siv cov yas uas tsis lwj hauv tshav dav hlau. Tam sim no, txhua yam khoom yas uas tsis lwj tau raug hloov los ntawm lwm yam khoom siv uas lwj tau hauv cov khw muag khoom loj, cov khw noj mov, cov chaw so rau cov neeg caij tsheb, cov chaw nres tsheb thiab lwm qhov chaw hauv lub tsev davhlau ya nyob twg, thiab cov dav hlau neeg caij tsheb hauv tebchaws tau tso tseg kev muab cov khoom siv yas uas tsis lwj pov tseg, cov pas nrig sib xyaw, cov hnab ntim khoom, siv cov khoom yas uas lwj lossis lwm yam khoom siv uas siv pov tseg. Paub txog kev "tshem tawm" cov khoom yas uas tsis lwj, thiab "thov tuaj rau hauv" rau lwm yam khoom siv uas tsis ua rau ib puag ncig puas tsuaj. -
PP resin yog dab tsi?
Polypropylene (PP) yog ib yam khoom siv thermoplastic uas tawv, tawv, thiab siv lead ua. Nws yog ua los ntawm propene (lossis propylene) monomer. Cov roj hydrocarbon linear no yog cov polymer sib dua ntawm txhua yam khoom yas. PP los ua homopolymer lossis copolymer thiab tuaj yeem ua kom muaj zog nrog cov khoom ntxiv. Polypropylene tseem hu ua polypropene, yog cov thermoplastic polymer siv rau ntau yam kev siv. Nws yog tsim los ntawm kev loj hlob ntawm cov saw hlau polymerization los ntawm monomer propylene. Polypropylene yog ib feem ntawm pawg polyolefins thiab yog ib feem crystalline thiab tsis yog polar. Nws cov khoom zoo ib yam li polyethylene, tab sis nws nyuaj me ntsis thiab tiv taus cua sov ntau dua. Nws yog cov khoom dawb, mechanically rugged thiab muaj kev tiv taus tshuaj lom neeg siab. -
