Preshrinking tshuab yog cov cuab yeej siv ua tiav rau npuag cov tshuab kho kom zoo nkauj hauv cov khaub ncaws niaj hnub ntau lawm. Hauv qee qhov kub thiab txias, av noo thiab siab qhov xwm txheej, nws tuaj yeem tshem tawm qhov muaj peev xwm shrinkage feem ntawm cov khaub ncaws ntaub los ntawm txhais tau tias ntawm elastic shrinkage deformation ntawm cov ntaub nws tus kheej thiab nkag mus thiab o txoj ntsiab cai ntawm cov ntaub thiab fiber.
Feem ntau, lub tshuab preshrinking tuaj yeem siv rau preshrinking ntawm cov paj rwb ntshiab, tshuaj fiber, blended ntaub thiab woolen ntaub. Tam sim no, muaj ob yam preshrinking tshuab nquag siv nyob rau hauv kev lag luam kev ua lag luam nyob hauv Suav teb, piv txwv li roj hmab pam preshrinking tshuab thiab pam preshrinking tshuab.
Txij nkawm ntawm lub tshuab preshrinking
Hauv kev tsim khoom niaj hnub no, kev tu txhua hnub ntawm lub tshuab preshrunk yog tsuas yog rau peb ntu: kis, ua haujlwm thiab tsav.
Ua ntej tshaj plaws, rau kev xa cov kis ntawm lub tshuab preshrinking, peb yuav tsum kuaj xyuas lub iav tsav thiab sprocket tsis tu ncua, thiab yog tias peb pom qhov hnav hnyav, peb yuav tsum tshem tawm thiab hloov lawv sijhawm. Ib qho ntxiv, rau qhov seem uas yuav tsum tau ntxiv roj, peb yuav tsum ntxiv cov roj lubricating tshwj xeeb kom tsis tu ncua kom paub meej tias qhov kis ntawm lub tshuab preshrunk tau nyob rau hauv qhov zoo lubricating.
Thib ob, rau kev ua haujlwm, peb yuav tsum ntxuav cov roj hmab pam thiab pam vov lub sijhawm twg los tau, thiab tshem lub impurities ntawm daim pam saum npoo nyob rau sijhawm. Yog tias siv lub conveyor siv ntawm kev ua haujlwm ntawm cov cuab yeej pom pom tias muaj hnub nyoog lossis hnav, peb yuav tsum tau hloov txoj siv conveyor hauv lub sijhawm.
Thaum kawg, rau txoj kev tsav, peb tsuas yog yuav tsum tau ua ntu zus thiab tshem tawm cov plua plav thiab daim ntaub khib nyiab hauv lub tshuab tsav kom tsis pub tawm.
Cov teeb meem nquag ntawm preshrinking tshuab thiab lawv cov kev daws teeb meem
Tsis txaus ntaub shrinkage:
Vim tias cov ntaub txav ceev ntawm lub tshuab preshrinking ceev heev, lub sijhawm ntawm cov ntaub hauv dej tsis ntev ntev, thiab qhov kub tsis dhau; conveyor txoj siv ntawm cov roj hmab pam thiab pam yog nyias dhau; txoj kab uas hla ntawm lub tshuab cua sov loj dhau lawm thiab yog li ntawd yuav cuam tshuam rau preshrinking tus nqi ntawm cov ntaub. Peb tuaj yeem txhim kho qhov kub thiab txias los ntawm kev maj mam txo qhov kev sib tw ntawm cov ntaub kom yog, hloov cov tuab txoj kev sib tw, hloov pauv cov cua sov thiab lwm yam los daws qhov teeb meem ntawm cov ntaub preshrinking txaus cov lus nug. (Nco tseg: lub thickness ntawm conveyor txoj siv yog feem ntau 25.5mm-67mm; lub taub ntawm cov cua kub roller yuav tsum tsis pub dhau 300mm-350mm.)
Kev cuam tshuam los yog puas los ntawm daim pam roj hmab lossis pam:
Cov laj thawj tseem ceeb rau qhov teeb meem no: muaj qee qhov teeb meem zoo hauv cov roj hmab pam thiab pam nws tus kheej, qhov kev ncua deb ntawm cov pub menyuam thiab lub tshuab cua sov, nyob nruab nrab ntawm cov menyuam pub thiab cov cua sov rau cov menyuam tsis tau raws li qhov yuav tsum tau ua, qhov curvature ntawm daim pam vov hloov, qhov chaw nruab nrab ntawm cov khoom noj pub mis thiab cov menyuam cua kub yog nyob rau tib txoj kab, qhwv lub kaum sab xis yog qhov loj tshaj plaws, thiab daim pam siv yog yooj yim raug puas ntsoog. Txhawm rau tshem tawm qhov txhaum no, tus neeg teb xov tooj tuaj yeem hloov cov roj hmab pam thiab pam ntawm cov qauv zoo; yog hais tias qhov tuab ntawm daim pam siv xov yog 25 hli, tom qab ntawd peb yuav tsum kho qhov kev ncua deb ntawm qhov pub cov menyuam thiab cua sov rau cov menyuam kom txog 25 hli ~ 33 hli; yog hais tias qhov kev ncua deb ntawm qhov pub rau cov menyuam thiab cua sov rau cov menyuam yog 25 hli ~ 30 hli, peb yuav tsum kho lub nruab nrab ntawm lub taub hau pub mis thiab cua sov rau cov menyuam kom qhov chaw nruab nrab ntawm cov taub cua sov yog 1 hli siab dua qhov nruab nrab ntawm cov menyuam pub thiab li ntawd.
Qhov tshwm sim ntawm "tom" tshwm sim thaum daim ntaub saum npoo tilts rau pem hauv ntej:
Qhov no feem ntau yog vim qhov tseeb tias nyob rau hauv thiab tawm daim ntaub roller ntawm lub tshuab preshrinking tsis sib thooj nrog cov cua kub cua sov, thiab cov kev taw qhia ntawm cov ntaub nkag mus rau hauv txoj siv pam tsis yog nyob rau hauv txoj kev qhia tangent. Yog li, peb tuaj yeem kho cov kev sib txig sib luag ntawm cov ntaub qhwv sab hauv thiab sab nraud thiab cov cua kub cua sov, thiab kho cov kev taw qhia ntawm cov ntaub mus rau hauv txoj siv pam, kom nws daws tau qhov teeb meem no yooj yim.
Thaum cov hauv thiab tawm faib chais thiab cua sov rollers tig, qee qhov ntawm lawv:
Los ntawm kev tsom xam, muaj peb lub laj thawj rau qee ntu kev poob siab ntawm kev nkag mus rau hauv thiab tawm cov menyuam thiab cua sov cov menyuam thaum lawv tig: thawj, cov khoom faib thiab tawm rau cov menyuam thiab cov cua kub tsis zoo sib xws lossis khoov thaum lub sijhawm ua haujlwm ntev; qhov thib ob, kis tau tus mob kis thiab tus txha caj qaum hnav hnyav; qhov thib peb, cov khoom siv hloov pauv thiab cov khoom siv qub qub tau tsis zoo ua kom raug. Kev pom ntawm peb qhov laj thawj no, peb tuaj yeem txhim kho txoj kev khoov puag ncig ntawm cov menyuam lub tog raj menyuam, hloov cov khoom hnyav hnyav thiab sprocket hauv lub sijhawm, kho qhov tsis tsim nyog lossis qhov tsis zoo thiab cov khoom siv thiab cov txheej txheem thiab lwm txoj hauv kev los tshem tawm cov khoom siv txhaum.
