1. Daim ntawv thov thiab kev npaj luv luv:
Cov khoom siv tshwj xeeb ntawm polypropylene txheej yog tsuas yog siv rau txheej ntawm polypropylene woven hnab thiab ntaub ntaub. Tom qab txheej txheej, woven hnab ua los ntawm txheej tuaj yeem siv ncaj qha yam tsis muaj lub hnab polyene. lub zog thiab tag nrho kev ua tau zoo ntawm lub hnab woven yog zoo dua vim hais tias cov polypropylene ncig zaj duab xis yog ncaj qha coated rau ntawm lub hnab woven, thiab kev siv yog yooj yim, thiab cov nqi raug txo.

Lub Tsev Haujlwm Saib Xyuas Khoom Siv Hauv Lub Xeev (National Building Materials Bureau) tau tsim cov lus & lt; 1997>No.079 thaum lub Kaum Ib Hlis 1997, qhia tias lub hnab laminated woven yuav tsum siv rau ntim cov cement thiab lwm yam khoom. Nyob rau tib lub sijhawm, nrog kev txhim kho ntawm kev lag luam ntim khoom hauv tsev, kev siv ntau thiab ntau npaum li cas ntawm cov xim PP maj mam nthuav dav. Thawj cov chaw tsim khoom yas tau yuav cov kab ntau lawm ntawm cov hnab yas thiab cov hnab ntim khoom sib xyaw, hloov los ntawm thawj PE puab lub hnab PP woven hnab rau ob-hauv-ib lub hnab npog thiab peb-hauv-ib lub hnab yas sib xyaw, thiab kev lag luam xav tau ntawm qib PP yog ib hnub zuj zus. Cov xim hauv tsev PP khoom yog nruj.
muab cov saum toj no, peb raws li dav T30S thiab 2401 (MFR = 2 ~ 4 g / 10min) thiab ua tiav cov ntaub ntawv tshwj xeeb ntawm txheej txheej (MFR = 20 ~ 32 min, tensile zog 24.0 MPa) los ntawm kev tswj degradation tom qab sib tov.

Thaum lub sij hawm txoj kev loj hlob, ob peb thwmsim tau ua nyob rau hauv kev xaiv ntawm molecular hnyav regulators thiab lwm yam excipients, sib tov thiab plasticizing ntawm raw cov ntaub ntawv thiab cov txheej txheem tsis. Tom qab kev soj ntsuam zoo, kev tsim thiab txheej txheem ntawm PP txheej tau txiav txim siab. tsim cov kab ntau lawm. Cov txiaj ntsig tau txaus siab tau txais los ntawm ntau daim ntawv thov, uas ib txwm muaj kev cuam tshuam qhov ruaj khov ntawm cov khoom, zoo yaj fluidity, zoo li zaj duab xis tsim, tsawg shrinkage, siab tev lub zog thiab siab adhesion. 2. projected economic txiaj ntsim:

Tus nqi ntawm cov ntaub ntawv tshwj xeeb ib tuj txheej yog kwv yees li 2,000 yuan siab dua tus nqi ntawm cov khoom siv raw. Tom qab txiav cov khoom siv, kev ua haujlwm, kev siv hluav taws xob, kev txo nqi thiab lwm yam nqi ntawm 150 yuan, cov nyiaj tau los ntawm ib tuj ntawm cov khoom tshwj xeeb yog 1500 yuan. Cov zis txhua xyoo ntawm cov kab ntau lawm (xws li extruder nrog cov ntsia hlau taub ntawm 65) yog 350-450 tons, thiab cov se txhua xyoo tuaj yeem ncav cuag ntau dua 500000 yuan. Yog tias koj siv cov ntsia hlau loj extruder, cov khoom tsim tau ntau dua. Tam sim no, Tuam Tshoj muaj ntau tshaj 1000 lub hnab ntim khoom loj, cov zos thiab cov nroog thiab cov lag luam ntiag tug suav tsis txheeb. Qhov project muaj kev cia siab dav.
Thib ob, kev npaj technology ntawm polypropylene txias masterbatch polypropylene txias masterbatch yog polypropylene-based masterbatch, feem ntau yog siv los txo qhov kub ntawm polypropylene spinning thiab yas khoom hauv kev ua, tshwj xeeb tshaj yog nyob rau hauv polypropylene spinning zoo heev, tab sis kuj siv nyob rau hauv zus tau tej cov polypropylene tshuab. zaj duab xis, textile hnab, monofilament, txhaj tshuaj molding khoom kuj tau txais txiaj ntsig zoo.
Kev ua haujlwm tseem ceeb: ntxiv 1 ~ 5% cua txias masterbatch rau polypropylene cob rau kev ua haujlwm; tuaj yeem ua tiav cov ntsiab lus hauv qab no: txhua qib ntawm polypropylene cob tuaj yeem tsim cov khoom zoo C puag ncig zoo denier fiber ntau. Qhov kub thiab txias ua cov yas yuav raug txo los ntawm 20 ° C mus rau 50 ° C; txhim kho qhov zoo ntawm polypropylene fiber ntau thiab cov khoom yas; txhim kho ntau lawm efficiency; thiab txo cov pa phem ib puag ncig.

Scope ntawm daim ntawv thov: polypropylene spinning, polypropylene zaj duab xis tshuab, polypropylene woven hnab, monofilament
