Raug ib yas preform yog cov txheej txheem ntawm kev tsim cov hlais fiber ntau threads, feem ntau yog ua los ntawm iav, rau hauv mats uas yuav ua haujlwm ntxiv rau cov txheej txheem yas molding.
Yog li ntawd, dab tsi yog qhov preform?
Ib PET preform yog ib lub raj zoo li cov yas uas yog tsim los ntawm cov txheej txheem hu ua txhaj moulding, siv cov yas hu ua PET. Meanwhile lub pwm yog ib tug zoo li tus hollow daim ntawm hlau, ib lub cuab tam, uas yog siv los tswj cov duab ntawm cov khoom raug moulded.
Tsis tas li ntawd, lub raj mis preform yog dab tsi? Tag nrho cov yas soda los yog "pop" fwj pib li asmall yas raj hu ua a preform . Thaum no preform yog rhuab thiab tshuab mus rau hauv ib lub raj mis cov duab, itis npaj kom puv nrog koj nyiam dej haus carbonated. Thepolymer nyob rau hauv peb cov me nyuam dej qab zib lub raj mis preforms yog polyethyleneterephthalate, feem ntau hu ua PET.
Ntxiv mus, PET preform manufacturing yog dab tsi?
Preform yog tsim orshape ib yam khoom mus rau ib tug preliminary puab thiab loj. Hauv cov lus yooj yim rau PET Preforms tus Tsiaj (Polyethylene Terephthalate) cov ntaub ntawv yog tsim los rau cov duab uas zoo li molded rau ib qho tshwj xeeb uas yog tom qab ntawd tshuab mus rau lub raj mis hauv tshuab tshuab.
PET molding yog dab tsi?
Tsiaj yog cov ntawv luv rau polyethyleneterephthalate yas resin. Tsiaj muaj qhov melting point ze 270 ° C, thaum lub molding Qhov kub yog 270 txog 280 ° C, thiab yog li nws txhaj tshuaj molding yog ua nyob rau hauv arelatively siab kub. Ib qho ntawm cov yam ntxwv ntawm cov yas no yog nws qhov fluidity.

Dab tsi yog cov tswv yim thiab cov khoom tsim tawm hauv cov txheej txheem tsim khoom?
Hauv kev lag luam, yam tseem ceeb ntawm kev tsim khoom, peev txheej, lossis cov tswv yim yog qhov uas siv hauv cov txheej txheem tsim khoom los tsim cov khoom tawm - uas yog, cov khoom tiav thiab cov kev pabcuam. Tus nqi siv ntawm ntau yam inputs txiav txim seb qhov ntau npaum li cas ntawm cov zis raws li kev sib raug zoo hu ua ntau lawm muaj nuj nqi
Qhov kev pabcuam tsim khoom tsim khoom yog dab tsi?
Productivity yog qhov sib piv ntawm cov khoom tsim tawm thiab cov kev pabcuam thiab cov tswv yim ntawm cov peev txheej siv los tsim lawv. Qhov tseeb tias cov kev pabcuam kev lag luam tam sim no suav nrog ib nrab ntawm tag nrho cov kev lag luam tsim tawm tau coj peb mus rau qhov kev xav tias kev pabcuam-kev ua haujlwm yuav muab ib feem ntawm qhov kev piav qhia
Dab tsi yog qhov kev sib raug zoo ntawm tag nrho cov khoom tsim tau thiab cov khoom tsim tawm thawj zaug sau qhov sib npaug?
Koj tuaj yeem pom tias koj tus lej nyiaj hauv tuam txhab nyiaj tau txiav txim siab raws li hauv qab no: Koj qhov Net ntau lawm yog sib npaug rau koj qhov Kev Tsim Nyog Tag Nrho Tshem Tawm Tawm, uas yog tib yam li qhov sib npaug saum toj no uas hais txog Net Primary Production (NPP) = Gross Primary Production (GPP) Kev ua pa tawm (R)
Dab tsi yog qhov sib txawv ntawm ib qho kev xa khoom thiab ntau qhov kev xa khoom uas zoo dua yog vim li cas?
Ib qho kev nrhiav khoom tuaj yeem ua rau lub tuam txhab muaj kev pheej hmoo (piv txwv li, tus neeg muag khoom lub neej ntawd), tab sis, tib lub sijhawm, ntau lub tswv yim muab khoom nthuav tawm ntau dua cov nqi pib thiab tsis tu ncua vim xav tau kev tswj hwm ntau dua ib tus neeg muag khoom
Qhov feem pua ntawm VCT kev nqis peev yuav tsum tau ua hauv cov khoom tsim nyog lossis kev nyab xeeb hauv lub sijhawm tsim nyog?
Cov cai tseem ceeb yog: Tsawg kawg 80% ntawm lawv cov kev nqis peev yuav tsum yog hauv kev nqis peev uas tsim nyog - cov tuam txhab me (ntau tshaj £ 15 lab ntawm cov khoom muaj nqis) uas tsis tau hais los yog pauv ntawm AIM es tsis yog lub lag luam loj. Lawv yuav tsum tau nqis peev hauv cov tuam txhab hauv peb xyoos ntawm kev nce nyiaj tshiab
