Khw ntim chaw tsim tshuaj paus
1. Muaj ntau ntau yam, txhua tus muaj nws qhov zoo, kev ua haujlwm siab dua thiab dav kho kom yooj yim. Nws tuaj yeem siv cov yas ntau yam, tsim ntau yam, thiab txheej txheem sib txawv los tsim ntau cov yeeb yaj kiab-tib txheej nrog cov khoom sib txawv. Nws tseem tuaj yeem tau txais ntau pua hom kev sib txawv los ntawm kev sib txawv ntawm cov khoom siv. Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, ntau yam tshiab yuav nce sai, yog li nws muaj peev xwm txaus siab txhua tus ntawm lawv zoo heev. Kev thov rau kev ntim khoom sib txawv.
Khw ntim cov hnab ntim khoom lag luam thiab lawv cov khoom siv muaj ntau yam, muaj los ntawm cov khoom zoo ib yam lossis zoo sib xws, yog li cov khoom sib txawv kiag li tau muaj kev lag luam ntau lawm, xws li LDPE zaj duab xis thiab EVA zaj duab xis, uas muaj cov khoom zoo heev, thiab muaj kev pom zoo, yooj, tsis tshua muaj kub tsis kam, cov huab cua zoo permeability thiab kev nyiam huv. Qhov zoo ntawm kev yooj yim ntawm kev sib khi thiab lub hnab ua kom Canzi muaj qhov luv luv ntawm qhov tsis zoo thaum tshav kub tsis kam, tab sis qhov muag muag thiab tsis kub tsis kam ntawm EVA yog qhov muaj peev xwm ntau dua, thiab qhov kub tsis kam ntawm EVA yog qhov phem dua li ntawm LDPE. Tseem muaj ntau yam khoom nrog cov khoom sib txawv.
Piv txwv li, tsis tsuas yog polyolefin zaj duab xis nrog zoo heev dej tsis kam thiab noo noo tsis kam, xws li polyethylene, polypropylene, thiab lwm yam, tab sis kuj polyvinyl cawv zaj yeeb yaj kiab kom yaj thaum sov; muaj tsis tsuas yog cov yeeb yaj kiab tiv thaiv kev laus ua los ntawm cov mis ruaj khov, tab sis kuj muaj kev tiv thaiv ib puag ncig tiv thaiv cov yeeb yaj kiab uas tuaj yeem ua rau sai sai hauv lub sijhawm luv luv tom qab siv; muaj kev kub siab. Tag nrho cov yas hloov tau cov khoom ntim, tab sis kuj tag opaque (lub teeb-ntawv pov thawj) txhuas, ntawv thiab cov khoom yas; ob qho tag nrho siab gloss ntim cov ntaub ntawv ntim khoom, tab sis kuj ncua-hom ntau yam; ob qho tib si permeable zaj duab xis, tab sis kuj muaj ntau cov nyom, hauv cov nyom ntau yam, tab sis kuj muaj cov nyom siab, nruab nrab nruab nrab.
Cov khoom siv ntim sib txawv muaj cov khoom sib txawv. Los ntawm kev xaiv noj ntawm ntau yam, lawv tuaj yeem ua kom tau raws li qhov xav tau ntawm ntau cov khoom ntim. Tsis hais txog cov kev xav tau tshwj xeeb ntawm cov khw muag khoom niaj hnub, cov khoom siv textile, cov ntaub ntawv zoo nkauj, cov txiv hmab txiv ntoo thiab zaub tshiab, cov khoom noj ua noj thiab cov khoom lag luam tshuaj, kev siv cov ntaub ntawv ntim khoom noj khoom haus yas ntim khoom rau ntim tuaj yeem sib piv. Txaus siab daws.
2. Tsis tshua muaj noj cov khoom siv raw khoom thiab kev txuag lub zog. Lub tuab ntawm lub hnab yas tsim chaw me me, qhov dav dav tsuas yog 0.03mm-0.05mm, thiab qhov tsis zoo ntawm txhua cov square meter tsuas yog 30g-50g. Yog li, kev siv cov ntawv ntim khoom hloov pauv mus rau cov khoom ntim khoom tuaj yeem txuag kev siv nyiaj thiab kev siv ntau piv nrog lwm cov ntawv ntim.
3. Tsawg tus nqi. Raws li tau hais los saum toj no, cov ntaub ntim khoom ntim yas hloov khoom noj muaj qhov zoo ntawm kev noj tsawg ntawm cov ntaub ntawv raw, kev ua kom yooj yim, kev siv hluav taws xob tsawg thiab kev ua haujlwm siab, yog li lawv muaj cov yam ntxwv ntawm tus nqi qis.
Raws li cov ntaub ntawv ntim muag muag muaj ntau qhov zoo, ntawm cov muaj txiaj ntsig zoo tshaj plaws yog tias peb tuaj yeem tsim thiab tsim cov khoom xav tau thiab cov khoom ntim tshwj xeeb los ntawm kev sib txuam ua ke ntawm ntau cov ntaub ntawv, yog li lawv muaj kev ua tau zoo-nqe piv thiab qhia kev lag luam muaj zog sib tw, uas tau nyiam thoob plaws thiab nthuav dav. Nws npog ntau lub teb, xws li zaub mov, tshuaj, kev lag luam teeb, textile, khoom lag luam rau kev siv txhua hnub, thiab tau dhau los ua ib qho ntawm cov tseem ceeb tshaj plaws ntawm cov khoom ntim yas.
4. Lwm tus yooj yim khaws, thauj thiab siv.
