Qhov zoo ntawm aluminium qhov rooj thiab lub qhov rais profiles muaj ntau txoj kev txiav txim siab nrog txoj kev, thiab txawm tias tib daim ntawv, ntau hom kev ua haujlwm yuav ua rau ntau qhov rooj thiab qhov rai zoo. Ib qho tseem ceeb tshaj plaws rau kev txhim kho qhov rai txhuas profiles yog hermeticity. Rau cov neeg tau txais kev pab, yog tias lub qhov rooj kaw nyob hauv lawv cov tsev kaw lawm, cov khoom siv hluav taws xob thiab cov rwb thaiv tsev tuaj yeem ua tiav, thiab yog tias qhov rooj thiab lub qhov rais tsis tuaj yeem, cov nyhuv rau lawv tsis zoo heev. zoo li.
Nyob rau hauv cov txheej txheem ntawm machining aluminium qhov rooj thiab lub qhov rais nrog tawg txuas hniav, tej zaum yuav muaj ntau cov ntsiab lus muab kev koom tes nyob rau hauv qhov chaw uas tsis muaj kev nruj ntse phenomena. Tom qab ntawd, qee leej kuj zoo ib yam li cov ces kaum (xws li lub qhov rooj ntawm qhov rooj thiab qhov rais), uas yog cov ntsiab lus tseem ceeb ntawm kev ua. Tam sim no, txhuas qhov rooj thiab cov qhov rais profile zoo ntawm kuj zoo Lawv muaj kev sib dhos siv cov khoom siv dag zog, vim hais tias lub tshuab nws tus kheej muaj qhov kawm siab heev ntawm qhov tseeb, yog li nws tuaj yeem txo qhov tshwm sim no, yog tias kev siv artificially assembled aluminium qhov rooj thiab qhov rais profiles, ces lub rooj sib txoos ntawm cov chaw tiaj no tsis zoo tag nrho.
1. Lub PVC daim duab siv los tsim cov khoom yas rau cov qhov rooj thiab qhov rais yog feem ntau yog ua los ntawm SG-5 hom, thaum raug tsim los ntawm kev siv cov tshuab rho tawm kev raug rho tawm. Qhov no yuav lav lub stability ntawm nws batch zoo, uas yog qhov Performance index.
2. Stabilizer plays lub luag haujlwm tseem ceeb hauv qhov zoo ntawm qhov profile nyob rau hauv tag nrho cov formulation system. Txoj kev ruaj ntseg ntawm kev sib koom ua ke thiab qhov sib ntxiv ntawm qhov sib ntxiv yuav cuam tshuam qhov ntev ntawm lub sij hawm yas ntawm cov khoom siv thiab qib ntawm cov khoom siv thermal decomposition. Qhov nqi koj tshuav ntawm qhov sib xyaw lubricating agent nyob rau hauv lub stabilizer yog qhov tseem ceeb ntsuas txog qhov zoo ntawm tus stabilizer.
Yog hais tias tus nab npawb ntawm cov stabilizers ntxiv yog siab, lub sij hawm yas yas ntawm cov khoom nyob rau hauv lub tog raj kheej thiab lub extrusion kub yuav qeeb. Qhov no yuav tsis txhais hais tias qhov pov thawj ntawm cov khoom siv nyob rau hauv hom kev tawm yuav tsis raws li qhov yuav tsum tau muaj. Nyob rau lub sij hawm no, tus brittleness ntawm cov profile yog heev. , yuav muaj kev cuam tshuam zoo rau txoj kev ua haujlwm vuam.
Yog hais tias tus nqi ntawm lub stabilizer tsawg dhau, lub sij hawm yas yas thiab cov thawv sov so ntawm cov khoom yuav luv, uas txhais tau hais tias cov khoom siv yuav ntau heev nyob rau hauv cov pwm, cov khoom uas tsis tshua tsim cov khoom ntim, tag nrho cov cuab yeej tawm dag zog yuav raug txo kom tsawg.
3. Qhov tseem ceeb ntawm CPE hauv qhov kev ua tus qauv yog los tiv qhov kev cuam tshuam thiab ua kom lub ntsej muag smoothness ntawm qhov profile. Txawm li cas los, qhov sib ntxiv ntawm qhov sib cuam tshuam tsis tau tsuas yog qhov feem zog thiab qhov hloov siab hloov, tab sis kuj lub zog ntawm qhov profile. Qhov no muaj feem xyuam rau tag nrho Qhov nqi koj tshuav ntawm kev muaj zog thiab kev sib yeem nyob hauv kev tsim qauv. Qhov sib ntxiv ntxiv yog feem ntau yog 8-15, qis dua 8 lossis tshaj saud 15 tsis zoo li qub.
Lub hauv paus ntsiab lus ntawm txoj haujlwm ACR yog txawv los ntawm CPE nyob rau hauv kev tsim cov qauv ntawm lub hauv paus molecular. Hais lus nruj heev, PVC / ACR sib tov yog qhov zoo tshaj rau PVC / CPE sib tov kom tsis tu ncua ua haujlwm.
4. Qhov tseem ceeb ntawm kev ua hom ACR yog los txhim kho cov yas ntawm cov khoom siv, thiab cov nplaum yog qhov sib thooj rau tus stabilizer. Hauv qhov tseeb, ob lub tswv yim yog txawv kiag li: tus stabilizer yog los tiv thaiv qhov degradation ntawm cov khoom; ACR yog los txhawb qhov kev daws teeb meem ntawm cov khoom siv. Lub sib haum xeeb. Ib co phenomena: zoo li nce tus nqi ntawm stabilizer thiab nce tus nqi ntawm ACR, tab sis nws yuav daws tau qee cov teeb meem kev ua haujlwm nyob rau saum npoo, nws tsis yog lawm nyob rau hauv tag nrho cov qauv tsim. Tus nqi ntawm ACR nyob ntawm koj txoj kev khwv noj qab haus huv thiab cov cuab yeej lub peev xwm los ua kom zoo.
Lub hauv paus tseem ceeb hauv kev tsim ntawm tag nrho cov profile yog cov neeg feem ntau hais txog kev sib koom tes. Lub degree ntawm plasticization ncaj qha cuam tshuam tag nrho cov ntsuas ntawm lub profile.
5, calcium carbonate feem ntau yog siv los qhib lub teeb, thiab nws cov nyiaj yog qhov thib ob loj tshaj plaws cuam tshuam rau cov neeg kho tshuab zog ntawm tag nrho cov seem.
Cov kev kuaj pom tau hais tias kev sib ntxiv kom zoo ntawm kev nano-calcium zoo yuav txhim kho txoj kev txuas ntawm qhov profile rau qee qhov twg.
6, kev xaiv cov roj nplaum yog qhov sib txuam nrog lub stabilizer, nyob rau hauv lub siab, lub roj nplaum yog ib qho chaw ruaj khov. Tus yuam sij rau lub rationality ntawm tag nrho cov formulation system yog lubrication tshuav, uas yog cov nyhuv synergistic ntawm qhov system stabilizer. Qhov tshwj xeeb tshaj yog thaum lub sab nraud roj nplua nyeem tob tob, nws yuav ncaj qha rau lub zog ntawm lub qhov rooj ntawm lub qhov rooj.
7. Cov xim tsis muaj kev cuam tshuam rau cov khoom siv dag zog ntawm qhov profile.
Kev cuam tshuam rau qhov zoo ntawm txhim kho qhov txhuas cov qhov rooj thiab cov qhov rais profiles tsis yog kev ua cov txheej txheem xwb, hom kev kho vajtse khoom tseem yog qhov tseem ceeb tshaj. Qhov no tawg ntawm txhuas qhov rai thiab qhov rooj qhov rooj nws tus kheej muaj kev xav tau siab dua rau txoj kev txuas, yog li qhov zoo ntawm cov khoom siv ncaj qha los txiav txim lub sealing ntawm qhov rooj thiab lub qhov rais. Yog li, yog qhov zoo ntawm cov khoom siv kho vajtse zoo dua, lub sij hawm rau qhov rooj thiab lub qhov rais yuav ntev dua, tiam sis tus nqi txhuas txhuas qhov rais thiab qhov rooj yuav qis me ntsis.
