Rov ua dua ntawm cov khib nyiab plastics - crushing
Khib yas yog ntau tshaj sau tau hu ua cov neeg siv khoom tom qab Yas nyob rau hauv synthesis, molding ua, kev sib tw yuav ua rau cov khoom siv khib nyiab, yooj yim yog lawv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tseem ceeb, cov khoom siv hluav taws xob tseem ceeb, cov khoom siv hluav taws xob tseem ceeb, cov khoom siv hluav taws xob kuj tau siv thiab siv cov khoom siv ncaj qha hauv kev tsim khoom. Yog li ntawd, feem ntau tau hais tseg khib nyiab yas feem ntau yog hais txog cov neeg siv khoom yas roj hmab.
Qhov crushing ntawm cov khib nyiab yas. Feem ntau cov khib nyiab plastics yuav tsum tau tsoo ua ntej sib cais. Thaum tu cov khoom loj loj ntawm cov thawv ntim cov hwj thiab cov neeg kho tshuab tu, nws kuj yog qhov tsim nyog los zus pov tseg; Nyob rau hauv cov txheej txheem dosing, txhawm rau kom ntseeg tau qhov kev faib tawm ntawm cov ntxiv, cov pov tseg yas kuj tseem yuav tsum tau tsoo. Txo nws qhov loj me rau ib qho kev kawm tau zoo; Nyob rau hauv melt granulation, kev pub ntawm extruder yog tsim rau cov khoom siv granular, thiab qhib zeb yog haum rau powdery lossis lwm yam duab ntawm cov khoom loj me me.
Cov duab ntawm cov khib nyiab plastics yog ua kom loj thiab qhov loj me yog sib txawv, sib tsoo lossis shearing txhais tau tias, ua ntej lawv tuaj yeem hloov kho ntau yam khoom siv tau rov ua dua tshiab. Rau qee cov khoom siv tsim khoom siv, xws li cov khib nyiab, khib nyiab thiab pov tseg los ntawm kev txhaj tshuaj thiab cov khoom siv tsis sib xws tom qab raug tsoo. Raws li cov zog sib txawv thov rau cov khoom siv, cov khoom siv tseem ceeb rau cov plastics tuaj yeem faib ua plaub pawg: compression, sib tsoo thiab tawv.
Kev xaiv ntawm cov khoom siv crushing thiab cov hniav feem tsuas yog nyob ntawm hom, cov qauv thiab qib ntawm crushing yuav tsum tau. Cov khoom sib txawv ntawm cov khib nyiab plastics yuav tsum tau siv cov khoom siv sib tsoo ntau, tawg ua ke, yog ib qho yooj yim, yog qhov cuam tshuam nrog cov khoom sib txawv, thiab cov cuam tshuam rau cov khoom sib tsoo yog qhov tsim nyog rau kev sib tsoo; Rau cov plastics nrog kev ua kom siab siab ntawm chav sov, xws li PE, ABS thiab lwm yam, nws yuav tsis siv brittle yas crushing khoom. Ib qho ntxiv, rau elastic, muag thiab tsawg-kub brittities cov ntaub ntawv, xws li muag muag pvc, nws yog qhov zoo tshaj plaws los siv cov khoom siv kub tsawg.
Ib qho ntxiv, cov khoom siv crushing yuav tsum tau txiav txim siab raws li kev kawm uas cov khib nyiab yuav tsum tau tsoo. Yog tias cov hmoov loj tawg ua tej daim me me, zaws, cuam tshuam lossis shear crushing cov khoom yuav tsum tau siv; Yog tias cov me me yog tsoo ua hmoov zoo, cov khoom zoo, sib tsoo cov khoom sib tsoo yog siv. Cov khoom loj lossis xav tau me me ntawm cov khoom zoo, feem ntau, feem ntau ua ntej tus coarser degree, thiab tom qab ntawd raws li qhov yuav tsum tau ua ntawm qhov nruab nrab lossis qib siab ntawm crushing.
Cov tsiaj tuaj yeem muab ntau hom crushing riam, kev daws teeb meem, nrhiav rau pem hauv ntej kom sib txuas lus nrog koj.
