Cov Khoom Siv Hluav Taws Xob: Cov Lus Qhia Xaiv rau PE Uas Tiv Thaiv Hluav Taws, PP Uas Tiv Thaiv Kub, thiab ABS Uas Tiv Thaiv Hluav Taws

Hauv kev tsim cov xov hluav taws xob, kev xaiv cov khoom siv cuam tshuam ncaj qha rau kev nyab xeeb hluav taws xob, lub zog kho tshuab, thiab lub neej ua haujlwm. PE, PP, thiab ABS yog peb yam khoom siv feem ntau siv. PE thiab PP feem ntau yog siv rau kev rwb thaiv tsev thiab lub plhaub hlau, thaum ABS feem ntau yog siv rau cov ntsaws thiab cov tsev.

I. PE (Polyethylene)
PEyog ib yam khoom siv rwb thaiv tsev hlau uas muaj kev rwb thaiv tsev zoo heev, yooj ywm zoo, tsis kub heev, thiab nqus dej tsawg heev. Nws tsim nyog rau kev siv mus sij hawm ntev los ntawm -40 ° C txog 80 ° C, ua rau nws zoo tagnrho rau kev rwb thaiv tsev sab hauv ntawm lub hwj chim hluav taws xob. PE tus qauv tsis yog hluav taws kub (oxygen index 17–18) thiab xav tau kev hloov kho hluav taws kub (piv txwv li, nrog magnesium hydroxide lossis txhuas hydroxide) kom ua tau raws li cov qauv kev nyab xeeb. PE siv rau cov txheej rwb thaiv tsev hauv cov hwj chim hluav taws xob, cov xov hluav taws xob, thiab cov xov hlau ntaub ntawv, thiab kuj tuaj yeem ua haujlwm ua lub thawv cable sib dua. Feem ntau nws tsis siv rau cov qhov ntsaws.

II. PP (Polypropylene)
PP ua tau zoo dua PE hauv kev tiv taus cua sov thiab lub zog kho tshuab. Cov qib hloov kho ua tiav qhov kub ua haujlwm ntev ntawm 100 ° C txog 105 ° C, nrog rau kev tiv taus kev ywj pheej zoo heev, tiv taus kev qaug zog, thiab kev ruaj khov tshuaj lom neeg. PP zoo heev rau cov xov hluav taws xob, cov xov hlau, thiab cov xov hluav taws xob nruab nrab mus rau qhov kub siab uas xav tau kev tiv taus cua sov thiab kev ruaj khov siab dua. Ib yam li PE, PP feem ntau yog siv rau cov ntawv thov xov hlau. Nws qhov kev ruaj khov thiab lub zog cuam tshuam qis dua ABS, thiab nws cov pwm shrinkage siab ua rau nws tsis haum rau cov qhov hluav taws xob ntsaws.

III. ABS
ABS yog ib hom yas engineering uas siv rau cov ntsaws fais fab thiab cov tsev. Nws muaj kev ruaj khov, tiv taus kev cuam tshuam, ruaj khov ntawm qhov loj me, thiab ci ntsa iab zoo heev, nrog rau kev ua haujlwm txhaj tshuaj zoo heev. Tus qauv ABS yog cov khoom siv hluav taws xob (oxygen index kwv yees li 18), yog li ABS uas tsis kub hnyiab tau raws li UL 94 V-0 lossis V-2 qib yog qhov yuav tsum tau rau cov ntawv thov fais fab. ABS tsis haum rau kev rwb thaiv tsev hlau thiab tsuas yog siv rau cov khoom yas sab nraud xwb.

IV. Cov Lus Qhia Txog Kev Xaiv
PE: Rau cov txheej rwb thaiv tsev hauv cov xov hluav taws xob, cov xov hluav taws xob, thiab cov xov ntaub ntawv uas xav tau kev rwb thaiv tsev zoo thiab yooj ywm. Yuav tsum siv PE uas tsis kub hnyiab.
PP: Rau cov xov hluav taws xob, cov hlua khi hluav taws xob, thiab cov xov hluav taws xob kub nruab nrab mus rau siab uas xav tau kev tiv taus cua sov thiab kev ywj pheej siab dua.
ABS Uas Tiv Thaiv Tau Hluav Taws: Rau cov ntsaws, cov qhov rooj adapter, cov hlua khi, thiab lwm yam khoom siv hauv tsev. Xaiv ABS uas ua tau raws li UL 94 qhov ntsuas tiv thaiv tau hluav taws.
Kev xaiv cov khoom siv kom zoo ua kom muaj kev nyab xeeb zoo tshaj plaws, kev ruaj khov, thiab kev zoo nkauj rau cov xov hluav taws xob.
