Yuav ua li cas kom khov cov chaw ntim khoom khov los ntawm kev tawg thiab tawg ntawm qhov kub tsawg?

Qaum txias kub heev; Lub thawv noj su yuav tsum muaj peev xwm tiv taus nws, nws tsis yog tsuas yog hais txog nws ntawm txoj kab. Koj yuav tsum paub tias qhov chaw kub tsis tshua muaj kev cuam tshuam rau cov plastics; Txwv tsis pub, lub npov noj su yuav khov thiab tawg, thiab cov zaub mov yuav nkim.

Dab tsi yog cov txiaj ntsig ntawm qhov kub ntawm cov yas molecules?

Yas yog qhov ua tau muaj ntau ntawm ntau cov hlua molecular. Nyob rau hauv chav tsev kub, cov saw hlau no hloov tau yooj yim, hloov tau. Tab sis ib zaug khov rau rho tawm kaum qib, cov molecular chains tawv thiab poob lawv yooj yim. Ib yam li iav zoo li no, nws ua tiav yooj yim. Qhov zoo tib yam uas tau ntsib ntawm qhov chaw kub me, tshwj xeeb tshaj yog cov uas tsis tau hloov kho, yooj yim dhau los tau nkig, thiab lub npov noj su tsis meej. Tshwj xeeb tshaj yog pob tshabNtshiab yas noj - tawm cov khoom noj khoom haus, uas yog nyias thiab nkig, muaj ntau heev rau cov teeb meem no.

Dab tsi yog cov nyom hauv cov saw txias thiab cia ib ncig?

Los ntawm lub Hoobkas rau cov neeg siv khoom, cov khoom noj khov yuav tsum mus txog ntau theem, xws li thauj los ntawm cov tsheb ciav hlau tub yees, khov hauv cov chaw khaws khoom, thiab tuav thiab chaw thau khoom. Thaum lub sijhawm cov txheej txheem, cov thawv noj su noj su yuav tau nyem, sib tsoo, lossis ntau piled li. Yog tias lub npov su yog nkig thiab crumbles ntawm qhov kov me me, nws tuaj yeem yog qhov teeb meem tiag tiag. Tshwj xeeb tshaj yog lub takeinday su lub thawv ntawv thiab ntim khoom noj, yog cov neeg siv khoom noj su, lub catering kev lag luam cov duab yuav tseem cuam tshuam.

Lub thawv noj su yuav coj cov teeb meem?

Cov thawv tawg tau nthuav tawm cov khoom noj rau huab cua, uas tuaj yeem yooj yim siv lossis tsis muaj kab mob. Cov neeg tau txais kev pab tseem yuav poob kev ntseeg hauv lub npe thaum lawv pom lub thawv noj su tawg. Cov khw noj mov thiab cov khoom noj khoom noj xav tau cov thawv noj mov kom nyob ruaj khov nyob ruaj khov kom lawv tuaj yeem ntseeg kev nyab xeeb rau lawv thiab lawv tus kheej lub koob npe. Tiv thaiv koj cov zaub mov thiab ua kom koj cov neeg yuav khoom zoo siab duaNtshiab yas noj - tawm cov khoom noj khoom hausuas ua tau zoo.

Cov khoom txiav txim siab seb lub thawv noj su puas tuaj yeem tiv thaiv khov thiab tawg. Cov hauv qab no yog qhov zoo thiab tsis zoo ntawm ntau cov ntaub ntawv ntawm kev ua lag luam.

Pp (polypropylene) {- pheej yig tab sis yooj yim rau khov, nkig

PP yog cov khoom siv yas uas pheej yig, pheej yig thiab cua sov {{}}}}}}}}}}}}} resist at at ntawm tsawg kub thiab tawg yooj yim. Txhawm rau txhim kho qhov kev ua yuam kev no, cov chaw tsim khoom yuav ntxiv qee qhov muag me ntsis thaum khov me ntsis thaum khov, tab sis nws tuaj yeem ua rau pob tshab yas ua kom zoo dua li.

Tus tsiaj - siab transparency, tab sis qhov ntsuas kub tsawg yuav tsum muaj zog

Tsiaj yog cov khoom siv ua kom ua cov khoom noj khoom haus pob tshab, nrog cov khoom zoo heev, haum rau kev ua zaub mov noj. Zoo tib yam tsiaj nyhav los ua nkig ntawm tsawg kub, yog li cov tuam ntxhab yuav siv nws cov ntaub ntawv los txhim kho nws cov khoom sib xyaw thiab anti- burnived muaj peev xwm. Lub txiaj ntsigNtshiab yas noj - tawm cov khoom noj khoom hausYog ob qho tib si zoo nkauj thiab khov - tiv taus, ua rau lawv xaiv nrov hauv cov ntaub txias ntim txias.

HDPE -} lub ntuj, qis- kub tiv thaiv tawv

HDPE tshwj xeeb yog qhov tshwj xeeb uas muaj qhov kub tsawg, thiab txias dua nws khov, qhov muaj zog nws tau txais los ntim nqaij khov, ua kom nqaij khov, thiab lwm yam zaub mov noj. Txawm li cas los xij, nws tsis yog pob tshab, thiab koj tsis tuaj yeem pom cov tsos ntawm cov zaub mov. Yog tias koj tsis xav tau cov zaub pob tshab, HDPE yog qhov kev xaiv zoo rau ntim khov.

Hloov Pulified Pla thiab pulp Composite - kev sim tshiab los ua phooj ywg zoo thiab khov {1} {resistant

Sta yog cov khoom siv biodegradable, ib puag ncig tiv thaiv, tab sis ntshai txias; Yog siv ib leeg, khov yog nkig yooj yim. Tam sim no muaj cov tuam txhab kev sib xyaw ua ke cov khoom siv PLA thiab mos mos lossis pulp, ua los ntawm ib puag ncig lub freezer lub freezer lub freezer lub freezer, tab sis tus nqi siab dua. Cov neeg siv khoom nrog cov tswv yim ib puag ncig uas siv cov hau kev sib xyaw no, nrog rau cov hau tshab rau cov yas ua kom pom tseeb yas.

Txhawm rau kom lub thawv noj su los ntawm kev tawg hauv lub freezer, nws tsis txaus ntseeg rau cov khoom siv; Tus qauv thiab cov txheej txheem yuav tsum tau ua kom zoo.

Cov Khoom Siv Hloov Kho yog qhov tseem ceeb

Ntxiv elastomers (zoo li poe, eva) rau cov yas tuaj yeem txhim kho kev nruj ntawm cov yas ntawm qhov kub tsawg, ua rau nws tsis tshua muaj tawg. Copolymers tseem tuaj yeem ua kom cov qauv molecular softer. Cov yas ntshiab nqa - tawm cov ntim khoom noj ua nyob rau hauv txoj kev no yog cov kev cuam tshuam ntau dua rau hauv lub freezer thiab muaj kev ntseeg siab ntau rau siv.

Tsim nyog tsim, tsis yog nyias nyias lub phab ntsa tuab

Hauv kev tsim cov khoom ntim khoom noj, cov fab yuav tsum tau sib npaug kom tsis txhob muaj cov ntse los ntawm kev ntxhov siab thiab ua rau tawg. Phab ntsa tuab tsim yuav tsum muaj khaub ncaws zoo nkauj; Tsis muaj qhov chaw nyias nyias, txwv tsis pub nws yuav yooj yim rau tawg thaum khov. Kev txhawb nqa tus tav kuj ua rau lub thawv noj su muaj zog. Clear Yas Siv - tawm cov ntim khoom noj yog tsim los tiv thaiv kom khov thiab nias.

Cov txheej txheem tsim khoom kuj cuam tshuam rau kev ua tau zoo

Tus ntsuas kub thiab txias yuav tsum tau tswj kev txhaj tshuaj molding. Txias txias dhau yuav ua rau muaj kev ntxhov siab sab hauv hauv cov yas, ua rau nws mus tawg. Lub sijhawm txias hloov kho, cov yas muaj ntau yam tsis muaj zog crystallization thiab zoo dua frostionance. Qee cov tuam ntxhab yuav ntxiv ib qho anti {{3} back batching txheej rau cov kev cuam tshuam noj su rau cov khoom noj su kom zoo rau cov khoom noj yog tsim nyog.

Koj tsis tuaj yeem tsuas yuav cov thawv noj su; Koj yuav tsum sib txuas qhov kev xav tau tiag tiag, them sai sai rau cov ntawv pov thawj, thiab xaiv cov tuam txhab tsim nyog.

Raws li kev siv ntawm qhov xwm txheej los xaiv cov khoom siv

Yog tias koj xav ua kom khov qee cov zaub mov hauv koj lub tub yees hauv tsev, tsuas yog xaiv PP lossis tsiaj; Rau kev lag luam tawm cov khoom xa tuaj, nws raug nquahu kom siv qis qis {{} {Reestant Tsiaj Copolymer lossis HDPE; Yog tias koj xav xa tawm mus rau cov cheeb tsam txawv teb chaws, koj yuav tsum tau them nyiaj tshwj xeeb rau cov khoom siv thiab xaiv qhov tsim nyog yas ua- tawm cov ntim khoom noj.

Saib seb cov thawv ntim khoom noj muaj cov ntawv pov thawj qis}}} kub sim

ASTM D746 Qes - urns orgittlement tuaj yeem ua pov thawj tias cov khoom ntim khoom noj kub me nyuam yuav tsis yooj yim tawg nyob rau hauv qis kub. Cov ntawv pov thawj no tuaj yeem ua pov thawj tias lub npov noj su tsis yooj yim tawg hauv cov kub qis. Thaum koj yuav lub npov noj su, koj yuav tsum nug cov ntawv pov thawj no, uas txhim khu kev qha ntau thiab tuaj yeem txo qis kev puas tsuaj.

Yangrui yog ib lub chaw tsim khoom tsim tshwj xeeb tshaj plaws hauv kev kub siab - Zoo whipable noj su thawv. Hu rau Yangrui rau kev daws teeb meem kom tau raws li koj cov kev xav tau ntawm qhov loj me, cov khoom siv, thiab kev tsim qauv.
