Qhov sijhawm ntawm qhov khoom, qhov stability, thiab qhov performance ntawm kev siv rau cov teeb meem txaus siab thiab lwm yam, yog tx based rau qhov durability ntawm qhov khoom, thiab qhov parameter ntawm qhov performance ntawm qhov khoom. Qhov design ntawm qhov khoom thiab qhov conditions ntawm qhov siv yog qhov cuab yeej uas txheem qhov durability, thaum li cas qhov molecular weight yog qhov tseem ceeb tshaj plaws uas txheem qhov durability. Qhov intrinsic viscosity tuaj yeem muab los txheem qhov molecular weight raws, thiab yog qhov convenient thiab reliable indicator thiab tool rau cov neeg siv los txheem qhov durability ntawm qhov khoom. Peb tus kws tshaj tso nyob rau Hangzhou Zhongwang Technology Co., Ltd., yog qhov company uas tau muab txais qhov certification ntawm national high-tech thiab yog qhov enterprise uas muaj ntau dua 80 qhov intellectual property uas tsis muaj kev sib txuas, peb design cov automated viscometry systems, thiab tuaj yeem siv cov automatic viscometers los txheem qhov durability ntawm qhov khoom los ntawm kev pabcuam qhov molecular weight ntawm qhov khoom.
Qhov Molecular Basis ntawm Durability
Nws kuj ua haujlwm tias qhov kev cuam tshuam ntawm kev nyuaj, kev ntxiv, thiab kev tswj hwm rau cov khoom tshuaj ntsuab. Cov khoom tshuaj ntsuab xwb—sib npog rau qhov nyuaj ntawm cov khoom tshuaj ntsuab thiab qhov nyuaj ntawm IV—tsis tuaj yeem sib cuam tshuam ntau dua los sis sib txuas ntau dua li cov khoom tshuaj ntsuab loj dua, uas ua rau cov khoom tshuaj ntsuab muaj kev nyuaj tsis zoo. Vim li no, rau cov khoom tshuaj ntsuab polyethylene zoo ib yam, qhov nyuaj ntawm IV, vim nws yog qhov tshuaj cim tias qhov nyuaj ntawm cov khoom tshuaj ntsuab, kuj tshuaj cim tias qhov polyethylene yuav nyuaj li cas.
Vim tias nws tshuaj cim cov khoom tshuaj ntsuab sib txuas rau hauv cov khoom tshuaj ntsuab thiab vim cov khoom tshuaj ntsuab loj tuaj yeem hlub, los sis sib txuas rau hauv cov khoom tshuaj ntsuab thiab tsis tuaj yeem haum los sis sib pab rau hauv kev tswj hwm rau kev puas los sis kev nyuaj (stress).
Yog li cas noj ntaus rau hauv qhov kev sib twb nyuaj ntawm cov polyethylene molecules uas nyuaj thiab yuav tsum muaj kev sib twb rau hauv qhov dav ntawm cov chain molecules. Yog li, tsis muaj dab tsi ua rau neeg xav tias yog koj xav ua cov luv luv polyethylene uas muaj kev nyuaj enough los pab rau kev nyuaj ntawm qhov khí, xws li cov khí uas nyob hauv cov luv luv uas muaj nqaij, koj yuav tsum ua cov luv luv uas muaj polyethylene terephthalate. Tiamsis, yog li cas, thaum koj pib siv cov polymers uas muaj kev nyuaj thiab muaj kev tswj hwm rau kev nyuaj thiab kev puas, koj yuav tsum siv lawv rau hauv qhov nyuaj siab.
Cov kev nyuaj thiab kev tswj hwm rau kev puas
Qhov yuav ntau dua ntawm qhov ntau ntawm kev tswj hwm ntawm cov khoom no tau pab txhawb rau qhov ntau dua ntawm cov kev ua haujlwm ntawm cov khoom uas pab txhawb rau kev tsis tuaj yeem nyob rau hauv kev siv. Piv txwv li, qhov ntau ntawm kev tswj hwm tau nyob rau hauv qhov ntau ntawm cov khoom thiab qhov ntau ntawm cov khoom yog qhov tswj hwm rau qhov ntau ntawm kev tswj hwm ntawm cov khoom. Qhov tsiag li no kuj muaj rau kev tswj hwm rau kev puas, qhov ntau ntawm kev tswj hwm rau qhov chaw puas thiab qhov ntau ntawm cov khoom rau qhov chaw puas.
Qhov ntau dua ntawm cov no thiab cov kev ua haujlwm lwm ob peb yuav nyob rau hauv qhov ntau ntawm kev tswj hwm ntawm cov khoom thiab qhov ntau ntawm cov khoom, thiab cov khoom uas tau ua los ntawm qhov ntau dua no yuav muaj kev nyob rau hauv kev siv zoo dua thiab yuav nyob rau hauv kev siv zoo dua kab mob los ntawm kev puas los yog kev tawg.
Kev tswj xyuam rau kev ntsuas (qhov cuab yeej los ntawm kev tswj xyuam rau kev ntsuas) yog kuj zoo dua rau cov khoom uas muaj qhov viscosity sib npaug. Cov khoom no tsis muaj kev txhawj xeeb rau kev ua haujlwm lossis kev ua haujlwm ntawm cov khoom rau ntej ntau. Qhov no yog qhov tseem ceeb rau cov khoom uas siv rau kev sib kooj lossis rau kev sib kooj uas muaj kev ntsuas.
Kev tswj xyuam rau kev ntsuas ntawm qhov chaw nyob
Kev ntsuas ntawm qhov chaw nyob yog qhov tseem ceeb uas muaj kev ntsuas rau cov khoom plastic uas siv rau kev sib kooj nrog cov khoom chemical uas muaj kev ntsuas lossis rau kev sib kooj hauv qhov chaw uas muaj kev ntsuas. Qhov tseem ceeb no muaj kev sib kooj ntawm kev ntsuas thiab cov khoom uas muaj kev ntsuas uas muaj kev sib kooj rau kev ntsuas thiab kev ntsuas rau cov khoom. Qhov viscosity ntawm polymer muaj kev sib kooj rau kev ntsuas ntawm qhov chaw nyob.
Tus, qhov ntau dua ntawm cov kab mob nyha yuav ua rau qhov tshwm sim ntawm kev pov tseg tsis ntau dua, thiab ua rau qhov kev pov tseg ntawm ESC yuav tsis ntau dua. Nws yog qhov tswv yim tseem ceeb los daws qhov tseem ceeb ntawm qhov ntaub ntawv thaum siv rau cov lus: cov kab mob ntawm lub tshuab, cov kab mob ntawm cov ntaub ntawv kim, cov khoom siv rau kev kho mob, thiab cov kab mob. Qhov kev pov tseg ntawm polyethylene yuav ntau dua thaum qhov loj ntawm cov kab mob nyha yuav ntau dua, yog li, kev soj qhov kev hloov ntawm qhov kev tshuaj ntsuag yuav pab txhawj xyuam qhov quality ntawm cov khoom uas yuav sib koom nrog cov ntaub ntawv kim.
Kev kho cov khoom thiab qhov kev ua haujlwm ntawm lub sijhawm ntev
Thaum kho cov khoom polymer, thaum cov khoom polymer tau txais qhov cua, tau txais qhov tshuaj ntsuag, thiab yuav tau txais qhov cua oxygen, qhov kab mob nyha yuav pov tseg, uas ua rau qhov loj ntawm cov kab mob nyha yuav nqis. Qhov kev nqis no yuav cuam tshuam rau qhov kev ua haujlwm thiab qhov kev nyuaj ntawm cov khoom uas tau kho xwb.
Kev pab tswv yeeb ntawm kev sib xyaw yog tuaj yeem pom ua ntej thiab tom qab kev sib xyaw kom cov neeg tsim kev sib xyaw tau paub txog qhov siab ntawm kev puas tsuaj, kom lawv tu kev sib xyaw raws li xav tau, uas txhais tau tias kev puas tsuaj yuav raug txo thiab kev nyab xaum ntawm cov khoom yuav zoo dua. Yog tias cov khoom no yuav siv rau hauv qhov chaw uas muaj kev nyab xaum siab heev (piv txwv li: cov khoom siv rau hauv rooj tsheb uas tau siv rau kev kawm, cov khoom siv rau hauv tsev, thiab cov khoom siv rau hauv kev kho mob), qhov kev sib xyaw no yuav tshwj xeeb dua.
Rau hauv qhov kev tshem tawm khoom, qhov no pab tau kev tsim cov khoom plastic uas tuaj yeem siv dua thiab nyab xaum los ntawm kev vam tswv yeeb zoo. Cov polymer tshem tawm yuav muaj kev puas tsuaj ntawm cov duab ntawm molecules los ntawm kev siv thiab kev sib xyaw ua ntej. Vim li no, cov neeg tshem tawm tuaj yeem txheeb xyuas qhov zoo ntawm cov khoom uas lawv tau txhais, thiab tsim cov khoom tshem tawm uas muaj qhov loom ntawm cov duab ntawm molecules uas xav tau, piv txwv li: vam tswv yeeb ntawm kev pab tswv yeeb ntawm kev sib xyaw, kom cov khoom thaum plav tau txhais tau qhov xav tau.
Cov hais txog
Kev ntxiv ntaus ntawm cov khoom plastic yog qhov tshwm sim rau kev ntxiv ntaus, thiab kev ntxiv ntaus uas tau muab txheeb xyuas yog qhov kev txheeb xyuas tseem ceeb rau qhov kev xam qhov loj ntawm cov duab haujlwm, thiab kev ua haujlwm ntawm cov khoom, kev tswj hwm rau kev ntxiv ntaus, thiab kev nyuaj siab thaum sib ntsib. Yog tias peb tuaj yeem tswj kev ntxiv ntaus raws li qhov tseem ceeb, ces peb yuav tuaj yeem tsim cov khoom uas tsis ntxiv ntaus thiab muaj kev ua haujlwm zoo heev, thiab lawv yog qhov xaiv rau cov teeb meem uas nyuaj heev. Hangzhou Zhongwang Technology Co., Ltd. muaj qhov viscometer tshiab uas tuaj yeem pab koj. Yog tias koj muaj kev xav, koj tuaj yeem hu rau peb cov specialist thaum twg li.
