Executive Summary
◆ Tsis yog ib qho Filler: Calcium carbonate (CaCO3) yog cov khoom siv tseem ceeb ntawm cov ntawv pob zeb, suav txog 70% txog 80% ntawm cov khoom kawg.
◆ Tus Nqi & Eco Advantage: Hloov cov ntoo ntoo ib txwm siv thiab txo cov khoom siv yas kom txo qis cov nqi raw khoom thiab tsim cov txheej txheem dej tsis muaj dej, tsis muaj ntoo.
◆ Qhov Kev Sib Tw Thaum Ntxov: CaCO3 yog abrasive heev. Standard extrusion kab yuav raug kev txom nyem ceev ceev thiab chim hnav. Cov tshuab tshwj xeeb thiab qhov chaw hloov kho CaCO3 yog qhov yuav tsum tau ua.
Introduction: Rewriting the Rules of Paper
Kev lag luam ntim thoob ntiaj teb yog nyob rau hauv lub siab loj heev los txo cov pov tseg yas thiab deforestation. Pob zeb ntawv (tseem hu ua pob zeb ntawv) tau tshwm sim los ua lwm txoj kev cuam tshuam.
Tab sis yuav ua li cas cov khoom siv pob zeb tuaj yeem hloov tau, luam tawm, thiab tsim kua muag? Cov lus teb yog nyob rau hauv kev ua haujlwm zoo ntawm Calcium Carbonate (CaCO3).
Rau cov tuam txhab B2B tab tom nrhiav nkag mus rau hauv kev ua lag luam no, nkag siab txog cov tshuaj lom neeg thiab lub luag haujlwm ntawm CaCO3 yog thawj kauj ruam mus rau cov khoom siv pob zeb muaj txiaj ntsig. Kab lus no rhuav tshem cov kev tshawb fawb tom qab lub pob zeb.
1. Cov Txheej Txheem: Vim li cas 80% Calcium Carbonate?
Pob zeb ntawv tsis yog ib yam khoom; nws yog ib qho kev sib xyaw. Kev lag luam-tus qauv formulation feem ntau muaj xws li:
70% - 80% Calcium Carbonate:Cov "pob zeb" (feem ntau yog muab los ntawm limestone, marble, los yog calcite).
15% - 20% Polymer Resin:Feem ntau HDPE (High-Density Polyethylene) los yog bio-based resins, ua raws li "binder."
2% - 5% Additives:Coupling agents, lubricants, thiab UV stabilizers.
Vim li cas thiaj li siab piv?
Economic Viability:CaCO3 yog ib qho khoom siv pheej yig tshaj plaws thiab muaj ntau tshaj plaws hauv ntiaj teb. Siv CaCO3 ntau dua txo tus nqi ib tuj piv rau cov yas yas.
Lub cev muaj zog:Cov pob zeb hauv av muab siab opacity (zoo meej rau kev luam ntawv), kev tsim kua muag zoo heev, thiab kev ntxhib los mos uas ua raws li cov ntawv sau.
Environmental Impact:Nws hloov cov ntaub ntawv ntoo, tsis tas yuav tsum muaj dej hauv cov txheej txheem tsim khoom, thiab cov ntsiab lus ntxhia siab txhais tau tias siv cov yas siv roj tsawg tsawg.
2. Chemistry: Kev hloov pauv ntawm qhov chaw yog tsis sib tham
Yog tias koj tsuas yog sib xyaw CaCO3 hmoov nyoos nrog cov yas yaj, qhov tshwm sim yog ib qho nkig, crumbling mess. Vim li cas? Vim tias calcium carbonate yog hydrophilic (dej-hlub), thaum polymer resins yog hydrophobic (dej-repelling).
Ua kom lawv sib xws, CaCO3 yuav tsum tau hloov kho qhov chaw (txheej txheem).
★Stearic Acid lossis Titanate Coupling Agents feem ntau yog siv los npog cov CaCO3 hais.
★ Cov txheej no txo qis lub zog saum npoo ntawm cov ntxhia, tso cai rau nws tawg mus rau hauv cov polymer matrix.
★ Qhov tshwm sim: Ib lub pob zeb zoo nkauj heev uas tsis muaj agglomeration (clumping) lossis micro-voids uas yuav ua rau kua muag.
3. Kev Sib Tw Machinery: Tswj Kev Sib Nqus (Kev Txawj Ntse)
Qhov no yog qhov uas ntau tus tshiab manufacturers poob. Calcium carbonate yog abrasive heev.
Thaum koj khiav ib qho sib tov uas yog 80% pob zeb los ntawm extruder, cov khoom siv zoo li cov ntawv xuab zeb ua kua.
★ Screw thiab Barrel Hnav:Txheem nitrided screws yuav hnav tawm hauv lub hlis. Koj yuav tsum siv bimetallic los yog tungsten-carbide-coated screws thiab chim.
★Tuag Design:Cov ntsiab lus siab muab tub lim nce yaj viscosity. Cov tuag yuav tsum tau tsim nrog cov kev khiav dej num tshwj xeeb los tiv thaiv stagnation thiab degradation ntawm HDPE binder.
★ Dispersion:Koj xav tau ib tug tshwj xeeb ntxaib-ntsia hlau extruder (los yog ib tug hnyav hloov ib leeg-ntsia hlau) los xyuas kom meej lub high-load CaCO3 yog zoo meej dispersed.
Ntawm Baoding Yashen Technology Co., Ltd., peb engineers peb lub Pob Zeb Ntawv Tshuab nrog cov kev cov nyom hauv siab. Peb siv cov khoom hnyav, hnav-tiv taus thiab kev cai ntsia hlau geometries tshwj xeeb uas tsim los ua cov khoom sib xyaw ua ke ntawm cov pob zeb hauv av.
Cov txheej txheem ntau lawm ntawm ib nrais muag
Txhawm rau pom li cas CaCO3 dhau los ua ntawv, ntawm no yog tus qauv txuas mus ntxiv:
[Phase 1: Compounding]
Modified CaCO3 + HDPE + Additives -> High-Speed Mixer ->Twin-Screw Extruder (Pelletizing)
[Theem 2: Zaj duab xis Extrusion]
Pellets -> Single-Screw Extruder -> T-Die (Flat Die) -> Cooling Rollers ->Thickness ntsuas

Engineering FAQs
Q: Dab tsi yog qhov loj me me (mesh) rau CaCO3 hauv pob zeb ntawv?
A: Feem ntau, 1250 txog 2500 mesh (kwv yees . 5 txog 10 microns) yog qhov zoo tagnrho. Coarse heev, thiab daim ntawv yuav hnov nkig thiab tsim kua muag yooj yim. Zoo heev, thiab cov khoom yuav agglomerate, ua rau dispersion nyuaj thiab nce lub tshuab siab.
Q: Cov ntawv pob zeb puas tuaj yeem siv dua?
A: Yog. Pob zeb ntawv yog # 2 cov yas rov ua dua tshiab (HDPE). Nws tuaj yeem yog av thiab rov ua dua. Txawm li cas los xij, vim nws cov ntsiab lus ntxhia siab, nws feem ntau tau sau rau hauv cov kev lag luam rov ua dua tshiab dua li cov qauv hauv nroog cov ntawv rov ua dua tshiab.
Q: Cov ntsiab lus CaCO3 siab puas cuam tshuam rau kev luam ntawv?
A: Ntawm qhov tsis sib xws, CaCO3 muab qhov zoo tshaj plaws opacity thiab matte tiav uas lees txais inks zoo heev. Txawm li cas los xij, qhov saum npoo yuav tsum tau kho nrog tus neeg kho Corona thaum lub sijhawm tsim khoom kom ntseeg tau tias tus number case adhesion.
Xaus: Daim ntawv qhia tsuas yog ib nrab ntawm kev sib ntaus sib tua
Calcium carbonate hloov pauv kev lag luam ntawm cov ntawv tsim khoom, tig pob zeb pheej yig rau hauv cov khoom ntim khoom kim heev. Txawm li cas los xij, qhov sib piv siab muab tub lim xav tau cov qauv tseeb thiab cov tshuab ua haujlwm ntev.
Baoding Yashen Technology Co., Ltd.muab cov kev daws teeb meem ua tiav. Peb tsis tsuas yog muab cov khoom siv hnyav pob zeb ntawv tshuab (extrusion kab) tab sis kuj muab cov ntaub ntawv pov thawj tshuaj rau kev hloov kho saum npoo thiab sib xyaw.
