Pulping yog ze ze rau qhov zoo ntawm daim ntawv. Raws li qib ntawm pulping nce, ntau yam khoom ntawm daim ntawv tau txais kev sib raug zoo thiab sib txawv. Cov kev cai nkhaus ntawm ntau yam khoom ntawm lub cev hloov pauv ntawm ob hom pulp zoo sib xws, qhia tias cov nyhuv ntawm pulping ntawm cov fibers sib txawv muaj ib txoj cai sib txawv, tab sis muaj qhov sib txawv me ntsis nrog rau ntau hom pulp. Lub slurry tom qab pulping kev kho mob yuav tsum tau tsim los ntawm Polyester Forming Screen Forming Fabric. Nws cov dej pom kev ua haujlwm zoo thiab cov qauv mesh ntawm Polyester Forming Screen Forming Fabric yuav tsum tau ua kom haum raws li qib ntawm pulping. Tsuas yog nyob rau hauv txoj kev no tuaj yeem lav qhov zoo ntawm cov nplooj ntawv tom ntej. High-zoo Polyester Forming Screen Forming Fabric tuaj yeem hloov kho kom zoo dua rau cov ntawv sib txawv ntawm cov qib pulping, pab txhim kho cov ntawv zoo. Lub caij no, Lub tiaj tiaj ntawm lub ntsej muag ntawm Polyester Forming Screen Forming Fabric tseem yuav koom tes nrog cov fiber ntau morphology tom qab pulping, ntxiv optimizing lub uniformity ntawm daim ntawv Xaiv qhov tsim nyog Polyester Forming Screen Forming Fabric yog tus yuam sij rau kev sib txuas cov txheej txheem pulping thiab molding.
(1) Kev sib raug zoo ntawm fiber ntau khi quab yuam thiab pulping
Nrog rau qhov nce ntawm pulping degree, qhov o thiab fineness ntawm fibers nce, qhov tshwj xeeb nto ntawm fibers expands, ntau hydroxyl pawg raug tso tawm, txhawb cov hydrogen bond ua ke ntawm fibers, thiab lub binding quab yuam ntawm fibers tsis tu ncua nce. Kev txhim kho ntawm lub zog sib txuas ntawm fiber ntau no yuav ua rau cov fibers sib cuam tshuam zoo dua thaum muab tshuaj txhuam los ntawm Polyester Forming Screen Forming Fabric, txo cov porosity ntawm daim ntawv.
Nyob rau theem pib ntawm pulping, qhov nkhaus ntawm fiber ntau khi quab yuam nce nrawm, qhia tias tus nqi ntawm fiber ntau o thiab kev loj hlob ntawm cov fibers zoo heev. Hauv nruab nrab theem ntawm pulping, qhov nkhaus ntawm fiber ntau khi quab yuam maj mam qeeb, qhia tias thaj tsam ntawm cov fibers tau raug nthuav tawm tag nrho, thiab qhov kev loj hlob ntawm thaj chaw fiber ntau tau dhau los ua qeeb. Nyob rau theem tom ntej ntawm pulping, qhov nkhaus ntawm fiber ntau sib khi quab yuam maj mam ncaj tawm, qhia tias cov fibers tau nqus dej heev, o thiab ua cov fibers zoo nyob rau theem tom qab ntawm pulping. Nws yog qhov nyuaj heev kom ntxiv qhov sib txuas ntawm cov fibers, yog li lub zog sib txuas ntawm cov fibers nce mus txog qhov kawg. Thaum lub zog sib txuas ntawm fiber ntau nce mus txog qhov kawg, qhov kev ua tau zoo ntawm Polyester Forming Screen Forming Fabric yog qhov tseem ceeb rau kev tswj xyuas cov txheej txheem kev ncaj ncees ntawm daim ntawv. High-zoo Polyester Forming Screen Forming Fabric tuaj yeem tiv thaiv cov ntawv sau los ntawm kev puas tsuaj.
(2) Kev tawg ntev
Qhov tawg ntev qhia qhov loj ntawm lub zog tensile uas daim ntawv tuaj yeem tiv taus. Nws yog xam raws li qhov kev xav tias ib qho kawg ntawm ib daim ntawv los yog cov duab los qhia ntawm ib qho dav yog raug tshem tawm, thiab qhov ntev tshaj plaws uas tawg vim nws qhov hnyav yog qhia hauv kilometers. Muaj ntau ntau yam uas cuam tshuam rau qhov ntev ntawm daim ntawv, feem ntau yog lub zog ntawm cov fibers thiab qhov nruab nrab ntev ntawm fibers. Nyob rau tib lub sijhawm, nws muaj feem xyuam rau kev sib cuam tshuam ntawm cov fibers thiab lub zog ntawm cov fibers lawv tus kheej. Nyob rau theem pib ntawm pulping, qhov tawg qhov ntev nce sai, tom qab ntawd maj mam qeeb, thiab tom qab ncav cuag tus nqi, muaj qhov tshwm sim ntawm kev tig thiab txo qis. Qhov no yog vim hais tias nyob rau hauv thaum ntxov theem ntawm pulping, qhov o sai thiab nplua fiber ntau tsim ntawm fibers nce lub zog ntawm cov fibers, thiab qhov tawg ntev kuj nce raws li. Nyob rau theem no, qhov tseem ceeb tshaj plaws uas cuam tshuam rau qhov ntev ntawm kev tawg yog lub zog khi ntawm cov fibers. Thaum lub℃ntawm pulping ntawm ntoo pulp yog nyob ib ncig ntawm 70℃SR thiab cov straw pulp yog nyob ib ncig ntawm 50℃SR, qhov tawg ntev mus txog nws qhov siab tshaj plaws tus nqi. Txuas ntxiv cov txheej txheem pulping, txawm hais tias lub zog sib txuas ntawm fiber ntau tseem nce ntxiv, vim qhov nruab nrab ntev ntawm cov fibers txo qis, qhov tawg ntev tau pib poob. Qhov tseem ceeb tshaj plaws cuam tshuam qhov kev tawg ntev hauv ntu tom kawg yog qhov nruab nrab ntev ntawm cov fibers. Lub sijhawm ntawm lub sijhawm tig qhov tshwm sim yog cuam tshuam nrog txoj kev pulping. Yog tias cov riam hnyav siv rau pulping, qhov ntev ntawm fiber ntau txo qis thiab qhov ntev ntawm cov pob txha rov ua ntej. Piv txwv li, thaum siv lub teeb riam rau pulping, tsawg fiber ntau yog txiav, uas yog qhov zoo rau kev ua kom tawg ntev thiab tseem ua rau lub sijhawm tig tom qab. Txoj cai variation ntawm kev tawg ntev kuj tseem muab cov ntaub ntawv siv rau kev xaiv qhov tsim nyog Polyester Forming Screen Forming Fabric qauv kom zoo dua rau cov ntawv sib sau nrog cov kev xav tau sib txawv.
