Kev tuav pov hwm kev ua haujlwm khau nrog roj hmab outsole muaj feem ntau hauv kev tuav pov hwm cov khau ua lag luam vim muaj cov yam ntxwv tshwj xeeb ntawm cov roj hmab. Txhawm rau kom ntseeg tau tias cov roj hmab outsole nkawm khau tuaj yeem hloov mus rau qhov tsis muaj plam, hnav-tiv taus, kub thiab hnyav ua haujlwm ib puag ncig, peb yuav tsum paub cov qauv ntawm cov roj hmab outsole los tsim cov roj hmab outsole tsim nyog.
Roj hmab formula technology yog kev tshawb fawb thiab kos duab ntawm kev xaiv thiab siv cov ntaub ntawv. Cov qauv roj hmab dav dav muaj peb lub hom phiaj: ua ntej, nws ua rau cov khoom siv roj hmab muaj cov khoom siv lub cev; thib ob, nws tuaj yeem koom tes nrog cov cuab yeej ua haujlwm uas twb muaj lawm rau kev ua haujlwm zoo; Thaum kawg, nws tuaj yeem ua tiav cov cuab yeej cuab tam lub cev uas ua tau raws li cov neeg siv khoom xav tau nrog cov khoom xyaw qis tshaj plaws. Hauv lwm lo lus, peb qhov tseem ceeb tshaj plaws uas yuav tsum tau xav txog thaum tsim cov qauv roj hmab yog lub cev ntawm cov khoom xyaw, kev ua tiav thiab tus nqi, thiab peb tau muab qhov sib npaug tsim nyog. Qhov no yog qhov tseem ceeb tshaj plaws ntawm kev tsim qauv qauv.
Additives feem ntau siv hauv cov qauv roj hmab tuaj yeem muab sau ua kaum lub ntsiab lus tseem ceeb:
Roj hmab los yog elastomers:
Thawj kauj ruam thiab tseem ceeb tshaj plaws hauv kev tsim cov qauv ntawm cov roj hmab yog xaiv cov roj hmab substrate los yog cov khoom siv kua nplaum. Roj Hmab yog ib yam khoom siv engineering, tsis hais txog nws qhov muaj pes tsawg leeg, nrog rau qee yam kev qhia yooj yim. Tag nrho cov roj hmab yog elastic, hloov tau, tawv, impervious rau dej thiab huab cua permeable. Ntxiv nrog rau cov yam ntxwv zoo li no, txhua cov roj hmab muaj nws tus kheej cov khoom vim nws muaj pes tsawg leeg.
Vulcanizing agents:
Lub hom phiaj ntawm kev ntxiv cov vulcanizing tus neeg sawv cev yog ua kom muaj tshuaj lom neeg cov tshuaj tiv thaiv ntawm cov khoom xyaw ua kom muaj kev sib txuas ntawm cov roj hmab molecules los hloov cov khoom ntawm lub cev ntawm cov roj hmab. Cov tshuaj tiv thaiv kab mob ua rau cov roj hmab sib txuas hloov los ntawm cov mos mos, khov, lub cev thermoplastic mus rau lub thermoset tawv, uas tsis tshua muaj kev cuam tshuam los ntawm qhov kub thiab txias. Sulphur tseem yog cov khoom siv dav siv ntau tshaj plaws rau hnub no. Lwm cov sulfur pub xws li TMTD (TUEX) ntawm thiuram disulfide yog qee zaum siv los ua ib qho kev tsim rau tag nrho lossis ib feem ntawm kev hloov cov tshuaj sulfur hauv cov sulfur uas tsis muaj sulfur lossis sulfur-free vulcanization system los txhim kho cov cua sov ntawm cov ntawv. Qhov thib ob tseem ceeb tshaj plaws txoj haujlwm ntawm tus tsim qauv yog kev xaiv ntawm vulcanization system, tus neeg sawv cev vulcanizing thiab accelerator.
Accelerators:
Lub vulcanization accelerator accelerates tus nqi vulcanization ntawm cov khoom xyaw thiab shortens lub sij hawm vulcanization.
Activators thiab retarders (Retarders):
Activators yog siv los pab txhim kho cov haujlwm thiab kev ua tau zoo ntawm tus accelerator. Feem ntau siv cov activators yog zinc oxide hmoov, stearic acid, lead oxide, magnesium oxide thiab amines (H).
Antidegradants:
Cov tshuaj tiv thaiv kev laus tuaj yeem ncua kev degradation ntawm cov khoom siv roj hmab vim muaj oxygen, ozone, cua sov, hlau catalysis thiab buckling motion. Yog li ntawd, qhov sib ntxiv ntawm tus neeg sawv cev tiv thaiv kev laus tuaj yeem txhim kho kev laus ntawm cov khoom thiab ua kom nws lub neej ua haujlwm ntev tom qab cov khoom xyaw ntxiv.
Kev pab cuam:
Cov khoom siv ua haujlwm, raws li lub npe qhia, pab cov khoom xyaw kom yooj yim rau kev ua haujlwm xws li kev sib xyaw, calendering, extrusion, thiab sib sau.
Fillers:
Fillers tuaj yeem txhim kho lub cev ntawm cov khoom xyaw, pab hauv kev ua haujlwm lossis txo lawv cov nqi. Kev txhawb nqa tuaj yeem ua rau muaj zog, tensile lub zog, modulus, tsim kua muag lub zog thiab abrasion tsis kam ntawm tsab xov xwm. Cov khoom siv ntxhia xws li soot lossis cov khoom zoo yog feem ntau siv.
Plasticizer, softener thiab tackifier (Tackfier):
Plasticity, softeners thiab tackifiers yog siv los pab cov khoom sib xyaw kom sib xyaw, hloov nws cov viscosity, txhim khu cov viscosity ntawm cov khoom xyaw, txhim kho cov khoom yooj yim ntawm qhov kub thiab txias, lossis hloov qee cov roj hmab tsis muaj kev cuam tshuam ntau dhau ntawm lub cev. Feem ntau, cov hom additives no tuaj yeem siv los ua cov khoom siv los yog cov khoom txuas ntxiv.
Xim Pigment:
Colorants yog siv nyob rau hauv non-carbon soot formulations los muab ib tug tshwj xeeb xim. Feem ntau siv cov ntaub ntawv xim tuaj yeem muab faib ua cov ntaub ntawv organic thiab inorganic. Inorganic hlau muaj xws li hlau oxide, chromium oxide, titanium dioxide (titanium dioxide), cadmium sulfide, cadmium selenide, barium sulfide, mercury sulfide, lithopone thiab tub rog xiav.
Organic pigments yog kim dua li cov xim tsis muaj organic. Txawm li cas los xij, nws siv tau zoo dua, cov xim yog ci thiab qhov tshwj xeeb lub ntiajteb txawj nqus tsawg heev. Ntxiv mus, cov xim hloov ntawm cov organic colorant yog ntau dua li cov khoom siv xim inorganic. Txawm li cas los xij, feem ntau cov organic pigments tsis ruaj khov rau chav, lub teeb, kua qaub lossis alkali thiab qee zaum tsiv mus rau saum npoo ntawm cov khoom.
Cov khoom siv tshwj xeeb:
Cov khoom siv tshwj xeeb yog cov khoom xyaw uas feem ntau tsis siv hauv dej, xws li cov khoom ua npuas dej, cov tshuaj tsw qab, cov khoom siv adhesion, cov nplaim hluav taws, cov kab mob mildew, thiab ultraviolet absorbers.
Daim ntawv qhia kev tsim qauv:
Yuav luag tag nrho cov formulations tshiab tau hloov kho los ntawm cov formulations uas twb muaj lawm. Tam sim no, ob peb tus neeg tau sim tsim cov qauv tshiab vim nws tsis xav tau kev xyaum. Txhawm rau kom cov qauv ua tau zoo, tus tsim qauv yuav tsum sim siv txhua yam ntawm cov ntaub ntawv uas yog cov khoom siv los yog extrinsic, tom qab ntawd teeb tsa thiab txheeb xyuas nws raws li qhov xav tau, thiab siv tus kheej lub tswv yim thiab muaj tswv yim los tsim cov qauv. Cov kauj ruam hauv qab no tuaj yeem siv los ua ib qho kev siv rau kev tsim qauv.
1. Txiav txim siab lub cev thiab cov nqi ntawm lub hom phiaj.
2. Xaiv cov khoom siv raw cov kua nplaum.
3. Tsim cov ntaub ntawv xeem rau cov khoom xyaw uas twb muaj lawm.
4. Xa mus rau cov ntaub ntawv qhia txog ntau hom ntaub ntawv.
5. Teem daim ntawv qhia thawj zaug.
6. Sim ua ib qho qauv me me los sim seb lub cev lub cev puas haum rau lub hom phiaj.
7. Kwv yees tus nqi ntawm cov ntaub ntawv siv los siv rau kev soj ntsuam ntxiv.
8. Ntsuas qhov ua tau zoo ntawm cov khoom xyaw no ntawm qhov chaw.
9. Sim lub hom phiaj nrog cov qauv no.
10. Kuaj seb lub cev lub cev puas tuaj yeem ua tau raws li qhov tshwj xeeb.
