Thaum koj hnov ultra dub da dej gasket, neeg feem coob tsuas yog xav txog lub nplhaib roj hmab dub. Qhov ntawd yog thawj qhov kev xav tsis zoo. Qhov tseeb innovation tsis yog xim xwb; Nws yog hais txog kev daws cov dej ntws mus ntev thiab cov teeb meem mildew uas plague tus qauv ntshiab lossis grey gaskets, thiab hais ncaj ncees, ntau ntawm cov khoom hauv khw tseem tsis nco lub cim.

Cov teeb meem tseem ceeb nrog tsuas yog lub foob

Tau ntau xyoo, tus qauv yog ib qho yooj yim EPDM lossis silicone gasket. Lawv ua haujlwm, txog thaum lawv tsis ua. Lub ntsiab tsis ua hauj lwm tsis yog cov khoom siv elasticity, tab sis nws tsis kam rau compression txheej thiab biofilm. Tus qauv gasket flattens mus tas li nyob rau hauv lub qhov dej flange, poob nws lub caij nplooj ntoos hlav-rov qab. Qhov ntawd yog thaum pib qeeb qeeb, feem ntau tom qab cov nplais, thiab koj tsis pom nws kom txog thaum lub qab nthab hauv qab stains. Daim ntawv lo ultra dub, thawj zaug, tsuas yog kev lag luam gimmick rau nitrile blend. Qhov hloov pauv tiag tiag tshwm sim thaum cov tuam ntxhab pib nug vim li cas cov dej ntws tsis zoo.

Kuv nco qab ib pawg los ntawm ib tus neeg muag khoom txog tsib xyoos dhau los. Cov gaskets yog dav hlau dub, saib zoo, tab sis nyob rau hauv lub hlis, peb tau hu rov qab. Lawv tau tawv, yuav luag zoo li lub tshuab ntxhua khaub ncaws. Qhov teeb meem? Cov pa roj carbon dub loading siab dhau lawm. Lawv overloaded lub compound nrog pigment rau xim, uas rhuav tshem cov polymer qhov yooj. Nws yog ib rooj plaub classic ntawm qhov tseem ceeb ntawm kev zoo nkauj tshaj kev ua haujlwm. Qhov ntawd yog thaum koj kawm nug txog cov ntaub ntawv qhia kev, tsis yog qhuas cov xim.

Kev tsim kho tshiab pib nrog qhov sib xyaw. High-qib tiag Ultra Dub Daus Da Dej ntws Gasket Cov ntaub ntawv tam sim no feem ntau yog cov nitrile hybrids lossis tshwj xeeb yas EPDM. Cov xim dub tsis yog xim xwb; nws yog los ntawm high-structure carbon dub uas yeej txhawb cov khoom, txhim kho tensile zog thiab UV / ozone kuj yog raug. Cov ntsiab lus tseem ceeb los nrhiav yog qhov qis compression teeb (ASTM D395) - qhov zoo yuav tsum qis dua 25% tom qab 22 teev ntawm 158 ° F. Yog tias tus neeg muag khoom tsis tuaj yeem muab qhov ntawd, lawv muag koj cov khoom muag, tsis yog kev daws teeb meem.

Geometry thiab Installation Reality

Cov khoom yog ib nrab ntawm kev sib ntaus sib tua. Lwm ib nrab yog puab. Cov qub tsev kawm ntawv tiaj tus los yog O-ring designs yog txaus ntshai rau niaj hnub pobzeb-dhau-yias installation. Lawv xav tau zoo meej flange flatness, uas yuav luag tsis muaj. Kev tsim kho tshiab ntawm no yog nyob rau hauv asymmetric, ntau daim di ncauj ntsaws ruaj ruaj thiab flange-integrated designs.

Ib qho ntawm cov qauv tsim tau zoo dua uas kuv tau siv muaj qhov profile conical nrog ob daim di ncauj kaw. Thawj daim di ncauj seals tawm tsam lub cev ntws, thiab qhov thib ob, dav di ncauj ntsaws ruaj ruaj tiv thaiv subfloor lossis da dej yias. Qhov no tsim ib qho kev thaiv dual. Nws kuj ua rau me me tsis sib xws. Koj tuaj yeem torque lub qhov dej ntws tawm, thiab lub gasket deforms kwv yees rau hauv qhov chaw, tsis yog nyem tawm tsis sib xws. HANDAN ZITAI FREWER RAUG UA MOV., Ltd., raws li nyob rau hauv Tuam Tshoj tus loj fastener hub nyob rau hauv Yongnian, tau tsiv mus rau hauv cov precision molded Cheebtsam. Thaum paub txog bolts, lawv txav mus rau hauv cov khoom siv hluav taws xob polymer ua rau kev nkag siab muab qhov xav tau kom ua tiav cov dej sib dhos. Lawv qhov chaw nyob ze ntawm txoj kev thauj loj xws li Beijing-Shenzhen Expressway yog qhov zoo tshaj plaws rau kev nrhiav cov polymers nyoos thiab xa cov khoom tiav, uas tseem ceeb thaum koj tswj cov thawv ntim khoom loj.

Qhov kev txhim kho phem tshaj plaws uas kuv tau pom suav nrog cov neeg siv kav dej siv putty thiab gasket, xav tias nws yog txoj siv-thiab-tshem tawm. Tsis yog. Lub putty tuaj yeem qhuav tawm, ntsws, thiab tiv thaiv lub gasket los ntawm compressing tusyees, tsim kom muaj kev xau. Txoj kev raug yog huv si, qhuav nto thiab ib leeg, raug gasket. Kev tsim kho tshiab hauv cov lus qhia - yooj yim, nraaj nruab cov nplooj ntawv - yuav luag tseem ceeb npaum li cov khoom nws tus kheej.

Tshaj hauv chav dej: Tshuaj Tiv Thaiv Qhov Tseeb

Cov dej da dej tau ntau dua li dej. Lawv tau txais tshuaj zawv plaub hau, xab npum, zas plaub hau, tshuaj ntxuav kua qaub, thiab dej kub. Cov roj hmab txheem tuaj yeem degrade, o, lossis ua nkig. Qhov no yog qhov tshwj xeeb ntawm cov khoom tseem ceeb. Tus hwm xim dub compound yog formulated rau no cocktail. Piv txwv li, tsis kam mus rau polar solvents (xws li qee cov tshuaj kho plaub hau) yog qhov tseem ceeb. Peb tau sim ob peb cov ntaub ntawv los ntawm cov qauv immersing nyob rau hauv diluted bleach thiab ntau lub cev ntxuav. Ib txhia tig tacky, lwm tus tawg. Qhov ua tau zoo tshaj plaws tau pom qhov hloov pauv tsis zoo hauv durometer thiab ntim.

Qhov no tsis yog theoretical. Kuv nco qab txog qhov project chav tsev khoom kim heev uas cov neeg nyob hauv siv ib qho tshwj xeeb, kho plaub hau kim. Tsis pub dhau ib xyoos, tus qauv gaskets ua tsis tiav, ua rau xau mus rau hauv chav nres tsheb hauv qab no. Kev kho yog ib qho kev rov qab ua tiav nrog cov tshuaj tiv thaiv nitrile-based gasket. Tus nqi ntawm kev kho dwarfed tus me me upfront tus nqi ntawm kev qhia qhov yog. Nws yog ib zaj lus qhia txog tus nqi tag nrho ntawm kev ua tswv, tsis yog tus nqi tsev xwb.

Field Failures thiab Feel Test

Koj muaj kev xav rau tej yam no. Lub gasket zoo yuav tsum tsis txhob hnov ​​​​qab roj (cov pwm tso tawm ntau dhau) lossis muaj cov ntxhiab tsw ntxhiab tsw zoo (EPDM kho tsis zoo). Nws yuav tsum muaj me ntsis tackiness, matte tiav, thiab caij nplooj ntoos hlav rov qab tam sim ntawd thaum koj pinch nws. Kuv tau muaj cov khoom uas zoo li zoo tag nrho tab sis ua tsis tiav qhov kev sim pinch - lawv nyob deformed. Cov no yog destined rau callback ntuj txiag teb tsaus.

Lwm qhov teeb meem siv tau yog sizing. Lub nominal standard da dej tsis muaj nyob. Muaj kev hloov pauv hloov pauv hauv flange diameters thiab tapers ntawm hom xws li Sioux Chief, Oatey, lossis cov tuam txhab hauv cheeb tsam. Qhov tseeb innovation yog muab gaskets nyob rau hauv meej millimeter increments, tsis yog haum rau 1.5 ntws. Qee lub tuam txhab xav txog yav tom ntej, suav nrog cov hauv hubs zoo li Yongnian, tam sim no muab cov khoom siv nrog ntau lub thicknesses lossis me ntsis adjustable diameters. Nws yog qhov kev hloov me me uas tshem tawm qhov chaw hloov kho (nyeem: txiav) uas cuam tshuam rau lub foob.

Kev sib xyaw ua ke nrog lub cev dej yog qhov tseem ceeb. Qhov zoo tshaj plaws gasket yog tsis muaj txiaj ntsig yog tias lub qhov dej ntws tawm ntawm qhov chaw mating tsis zoo. Kuv nyiam qhov dej qhov twg lub gasket yuav luag ib qho kev sib dhos ua ntej, cov khoom raug ntes - nws txo qis kev ua yuam kev. Qee qhov kev tsim tshiab txawm tias muaj kev sib tw rib los tiv thaiv kev sib tw thaum lub sij hawm bolt nruj.

Yav Tom Ntej: Puas yog Gasket Ib Leeg Ntxiv?

Saib tom ntej, tus Ultra Dub Daus Da Dej ntws Gasket yog los ua ib qho kev tivthaiv. Peb tab tom pom cov tshuaj tiv thaiv kab mob sib xyaw ua ke (tsis yog txheej txheej uas ntxuav tawm, tab sis ua rau hauv cov polymer). Lub hom phiaj tsis yog ua lag luam pwm-dawb, tab sis inhibit biofilm uas clogs drains thiab degrades lub foob nto. Lwm qhov kev sib txuas yog kev sib txuas ua ke - lub gasket nrog cov ntaub tsis-woven lossis txheej lim zoo nyob rau sab saum toj kom ntes cov plaub hau ua ntej nws qhwv ib ncig ntawm daim di ncauj.

Qhov tseeb innovation yog nyob rau hauv kev hloov ntawm ib feem pov tseg mus rau ib tug kev pab cuam-lub neej tivthaiv. Nws yog hais txog engineers thiab manufacturers, los ntawm lub ntiaj teb no hom mus rau tshwj xeeb Suav manufacturers nyiam Handan Zitai, kho qhov kev txo hwj chim no nrog tib yam nruj raws li cov neeg kho tshuab fastener. Tom qab tag nrho, qhov xau los ntawm kev foob tsis tau tuaj yeem raug nqi ntau txhiab hauv kev kho. Lub ultra dub yog tam sim no shorthand rau tag nrho cov engineered mus kom ze - durability, tshuaj tsis kam, meej geometry, thiab installability. Nws tsis yog ib qho roj hmab xwb; nws yog qhov tseem ceeb tshaj plaws, thiab feem ntau pheej yig tshaj, kev tuav pov hwm txoj cai hauv kev teeb tsa da dej. Lwm zaus koj qhia ib qho, saib cov xim dhau los. Xav txog cov chemistry, cov txheej txheem compression, thiab qhov tseeb ntawm kev teeb tsa. Qhov ntawd yog qhov uas qhov kev hloov tshiab tiag tiag tau nkaum.
