Cov khoom siv hauv tsev:
Nyob rau hauv xyoo tas los no, Tuam Tshoj txoj kev lag luam khoom siv hluav taws xob hauv tsev tau tsim kho sai, nrog ntau yam thiab cov khoom siv loj.Xyoo 2003, Tuam Tshoj tau tsim 18.5 lab lub tub yees, 42 lab cua txias, 17 lab lub tshuab ntxhua khaub ncaws, thiab 35 lab microwave ncu.Raws li "2004-2006 China Urban Home Theatre Market Research and Consultation Report", nws cia siab tias Tuam Tshoj lub tsev ua yeeb yam hauv tsev lag luam yuav ncav cuag 6.9 lab units hauv peb lub xyoos tom ntej.Tsis tas li ntawd, ntau yam khoom siv hauv tsev me me kuj muaj kev lag luam loj loj, uas yog lub sijhawm ua lag luam zoo rau kev hloov kho PP.Qee cov khoom siv yas hauv Suav teb tau tsim cov khoom tshwj xeeb rau cov tshuab ntxhua khaub ncaws, xws li PP 1947 series thiab K7726 series, uas tau txais tos los ntawm lub tshuab ntxhua khaub ncaws.Yog li ntawd, nyob rau hauv ob peb xyoos tom ntej no, kev txhim kho PP cov ntaub ntawv tshwj xeeb rau cov khoom siv hauv tsev yuav tsum tau nce ntxiv kom tau raws li qhov hloov pauv ntawm kev ua lag luam.
Cov yeeb nkab yas:
Nyob rau hauv 2003, lub teb chaws tag nrho cov zis ntawm cov kav dej yas tau tshaj 1.8 lab tons, ib xyoos ib zaug nce ntawm 23%.Thaum ntxov, cov kav dej PP feem ntau yog siv los ua cov kav dej ua liaj ua teb, tab sis kev lag luam tsis qhib vim qee qhov teeb meem ntawm kev ua haujlwm ntawm cov khoom thaum ntxov (kev cuam tshuam lub zog thiab kev laus tsis zoo).Nrog rau kev qhia txog kev siv tshuab txawv teb chaws los ntawm Shanghai Plastic Building Materials Factory, tom qab cov kav dej xa dej txias thiab dej kub ua los ntawm cov khoom siv PP-R tau raug lees paub los ntawm kev ua lag luam, ntau lub tuam txhab tau tsim PP-R yeeb nkab ntau lawm kab, thiab tus nqi kuj tau nce los ntawm cov kab ntau lawm.Tus nqi pib ntawm 20,000 mus rau 30,000 yuan / t tau txuas ntxiv mus, tab sis kev lag luam sib faib ntawm PP-R kav dej hauv cov yeeb nkab yas ua lag luam tseem tsawg heev.Raws li cov lus ceeb toom, tseem muaj qee qhov sib txawv ntawm cov khoom siv hauv tsev PP-R thiab cov khoom siv txawv teb chaws, thiab qhov zoo yuav tsum tau txhim kho thiab txhim kho.Raws li cov lus ceeb toom, Kaus Lim Qab Teb tau tsim cov qib tshiab ntawm random copolymer polypropylene PP-R 112 rau cov kav dej siab.Cov kav dej uas tsim los ntawm qib no tuaj yeem siv tau rau 50 xyoo nyob rau hauv ultra-siab siab ntawm 20 ° C thiab 11.2 MPa.
Cov kav dej yas yog ib qho ntawm cov khoom tseem ceeb rau kev nce qib thiab kev siv cov khoom siv hauv tsev hauv Suav teb.Lub Tsev Haujlwm Saib Xyuas Kev Tsim Kho tau tshaj tawm "Daim Ntawv Ceeb Toom Txog Kev Txhim Kho Kev Tswj Xyuas Kev Tsim Khoom thiab Kev Tshaj Tawm thiab Kev Siv Cov Khoom Siv Copolymerized Polypropylene (PP-R, PP-B) Pipes" nyob rau xyoo 2001, xav kom cov tuam tsev muaj feem cuam tshuam nrog kev ua haujlwm zoo hauv cov khoom siv raw, kev ua haujlwm, zoo thiab siv yeeb nkab siv, kev teeb tsa, thiab lwm yam, thiab nruj me ntsis tswj qhov zoo ntawm PP kav dej, thiaj li ua tau zoo dua ua haujlwm zoo hauv kev tsim, thov thiab txhawb nqa PP kav hauv Suav teb.
Cov ntaub ntawv pob tshab:
Nrog rau kev txhim kho ntawm tib neeg txoj kev ua neej nyob tsis tu ncua, nws yuav ua rau muaj kev sib txawv thiab kev txhim kho hauv ntau yam xws li kab lis kev cai, kev lom zem, zaub mov, kev kho mob, khoom siv, thiab kho kom zoo nkauj hauv chav.Ntau yam khoom hauv kev ua lag luam tau nce siv cov ntaub ntawv pob tshab.Yog li ntawd, kev txhim kho pob tshab PP cov ntaub ntawv tshwj xeeb yog ib qho kev txhim kho zoo, tshwj xeeb tshaj yog cov ntaub ntawv tshwj xeeb PP nrog cov pob tshab siab, zoo fluidity thiab nrawm tsim yuav tsum tau tsim thiab ua tiav rau hauv cov khoom nrov PP.Pob tshab PP yog cov yam ntxwv ntau dua li PP, PVC, PET, PS, thiab muaj qhov zoo dua thiab kev cia siab rau kev loj hlob.
Nyob rau hauv xyoo tas los no, kev lag luam pob tshab PP txawv teb chaws tau loj hlob sai.Piv txwv li, Kaus Lim Qab Teb tau tshaj tawm pob tshab PP rau kev ua lag luam los hloov PET;Qee lub tuam txhab German tau hloov PVC nrog pob tshab PP;kev loj hlob ntawm pob tshab PP khoom hauv Tebchaws Meskas yog 7% siab dua li cov khoom PP zoo ib yam ~ 9%;Nyob rau hauv xyoo tas los no, kev noj txhua xyoo ntawm PP nucleating thiab pob tshab tus neeg sawv cev hauv Nyiv yog kwv yees li 2000t.Yog tias qhov sib ntxiv yog 0.25%, cov khoom tsim tawm txhua xyoo ntawm pob tshab PP khoom hauv Nyiv tuaj yeem ncav cuag ntau dua 800,000t.Raws li kev taw qhia ntawm Nyiv Lub cev thiab tshuaj lom neeg Co., Ltd., Nyiv cov pob tshab PP cov ntaub ntawv tshwj xeeb yog siv rau hauv microwave cookers thiab rooj tog uas muaj kev noj ntau tshaj plaws.Nws kwv yees tias qhov kev thov rau pob tshab PP cov ntaub ntawv tshwj xeeb hauv kev lag luam txawv teb chaws hauv xyoo 2005 yog kwv yees li 5 lab rau 5.5 lab tons.Muaj qhov sib txawv loj ntawm cov pob tshab PP cov ntaub ntawv tshwj xeeb hauv tsev thiab txawv teb chaws, thiab kev tsim khoom thiab kev siv cov pob tshab PP resin thiab nws cov khoom tseem yuav tsum tau ntxiv dag zog.
