Nyob rau hauv niaj hnub science thiab technology, raws li zoo raws li nyob rau hauv ntau yam ntawm lub neej txhua hnub, qhov teeb meem ntawm kev sib txuas yog ubiquitous. Cov txheej txheem ntawm kev sib txuas xws li riveting, vuam, threaded kev sib txuas, ntsia hlau, thiab xaws tau siv rau lub sijhawm ntev. Txawm li cas los xij, tsis ntev los no txoj kev loj hlob ntawm cov nplaum thev naus laus zis nthuav tawm txoj hauv kev tshwj xeeb. Tshwj xeeb tshaj yog nyob rau hauv lub sijhawm ntawm polymers, kev loj hlob sai ntawm kev lag luam lim cua tau qhia txog lub luag haujlwm ntawm cov nplaum nplaum. Cov nplaum nplaum no muab qhov zoo tshaj qhov tsis tuaj yeem hloov pauv ntawm kev sib txuas ib txwm thiab kev sib khi, sawv cev rau kev tshawb fawb ntau dua, siv tau, thiab cov txheej txheem tshiab uas muaj txiaj ntsig zoo uas daws cov teeb meem tseem ceeb ntawm kev tsim khoom. Adhesives tau dhau los ua qhov tseem ceeb hauv kev lag luam huab cua lim.
1. Daim ntawv thov ntawm Adhesives hauv Frame Assembly- Bonding ntawm Paperboard / Lim Khoom / Hlau Ib qho piv txwv tseem ceeb ntawm cov ntxaij lim dej no yog cov lim dej tiaj tus hauv daim duab 1, nrog rau lub thawv hom lim. Paperboard, lim cov ntaub ntawv, thiab cov hlau hlau feem ntau yog cov ntaub ntawv hloov tau yooj yim, ua rau kev sib txuas ib txwm nyuaj. Adhesives ua rau cov txheej txheem no nyuaj. Emulsion-type adhesives feem ntau yog siv rau hauv cov txheej txheem no, thiab yog tias ua tau, cov nplaum kub yaj kuj tuaj yeem ua haujlwm. Cov txheej txheem curing rau emulsion-type adhesives feem ntau yog dej-raws li evaporation, uas yog cuam tshuam los ntawm kub thiab av noo, yuav tsum tau ib puag ncig zoo. Qee cov tuam ntxhab siv cov kua nplaum ua kua nplaum, uas yog qhov yooj yim dua los siv. Txawm li cas los xij, cov kev cai ib puag ncig tau ua rau muaj kev hloov pauv mus rau cov kua nplaum uas tsis muaj kuab lom. Raws li Huey Huey Lo los ntawm Kev Tshawb Fawb Kev Sib Koom Tes ntawm Lub Tsev Kawm Txuj Ci Kev Tshawb Fawb Hauv Kev Lag Luam hauv Taiwan hais tias, kev lag luam nplaum cov qauv tuaj yeem raug suav hais tias yog "tsawg tso tawm, kev ua haujlwm siab."
2. Daim ntawv thov ntawm Adhesives hauv hnab lim hauv hnab lim, kev sib khi ntawm rab koob-punched qhov khoob thiab kev sib txuas ib ntus ua ntej ntsia hlau sib dhos ob qho tib si qhia txog cov haujlwm tshwj xeeb ntawm cov nplaum. Kub-melt adhesives feem ntau yog siv rau sealing koob-punched qhov khoob, thaum dej-raws li evaporative adhesives los yog ib puag ncig tus phooj ywg hnyav-raws li adhesives yog siv rau kev sib txuas ib ntus ua ntej ntsia hlau sib dhos.
3. Daim ntawv thov ntawm Adhesives hauv Cua Lim- Pleating Thaum siv cov ntaub ntawv lim dej, tswj cov plua plav kom txaus (kev pabcuam lub neej) thiab kev ua haujlwm tsis zoo yuav tsum muaj cov ntawv lim kom ntau zaus ntau dua li qhov cua ntawm lub lim. Qhov no yuav tsum tau sib cais ntawm folded lim ntawv txheej. Adhesives ib zaug ntxiv ua lub luag haujlwm tseem ceeb hauv qhov no. Ua ntej xyoo 1970, cov duab los qhia dawb thiab cov ntawv txhuas feem ntau siv los ua cov khoom sib cais. Xyoo 1975, Sofilta lub tuam txhab pib siv cov latex-coated threads ua cov khoom sib cais. Nrog rau kev txhim kho thev naus laus zis, cov nplaum nplaum kub yaj tau maj mam ua haujlwm hauv xyoo 1990 los txhim kho pleat spacing, kom ntseeg tau qhov kev ncua deb ntawm txhua txheej ntawm cov ntawv lim. Kub-melt nplaum tuaj yeem hloov kho rau ntau yam tshwj xeeb, xws li kub tsis kam thiab nplaim taws, ua cov lim dej nrog kev ua haujlwm zoo. Nws yog feem ntau siv hauv kev tsim cov lim dej pleated, cov lim tsis sib cais, thiab qee cov lim tsev me me. Nws cov yam ntxwv muaj xws li odorlessness, high-temperature resistance, ceev bonding, tsis-nplaum kev ntxhib los mos, uniform dripping, thiab tsis kam mus nqus los ntawm lim ntawv.
4. Daim ntawv thov ntawm Adhesives hauv Cua Lim- Ntug Sealing, End Sealing, thiab Pleat Spacing Chemically reactive adhesives yog siv rau hauv cov ntsiab lus no. Epoxy resin adhesives tau nquag siv ua ntej, tab sis nrog kev qhia thiab kev txhim kho ntawm polyurethane nplaum thev naus laus zis, epoxy resin lub brittleness thiab tsis zoo cuam tshuam ua rau nws maj mam hloov los ntawm polyurethane. Nws yog tsuas yog siv nyob rau hauv manufacturing pleated lim, partitioned lim, non-partitioned lim, cartridge lim, thiab me me lim tsev. Qee lub tuam txhab kuj tseem siv cov nplaum nplaum kub rau kev sib khi ntawm ntug thiab pleat qhov sib txawv hauv qee yam khoom, xws li cov lim dej me me thiab cov lim cartridge. Cov nplaum tshwj xeeb xws li epoxy, silicone, heterocyclic polymer, thiab inorganic adhesives yog siv rau cov ntxaij lim dej nrog cov kev cai tshwj xeeb, xws li kub-resistant.
5. Daim ntawv thov ntawm Adhesives hauv Cua Lim- Kev sib txuas ntawm Gaskets thiab Sealing Strips Tom qab pib tsim cov lim cua, kev teeb tsa ntawm sealing strips lossis gaskets yuav tsum muaj cov nplaum nplaum. Kev xaiv ntawm cov nplaum yog nyob ntawm qhov xav tau lub zog. Tshuaj reactive adhesives xws li hnyav-raws li nplaum nplaum thiab instant adhesives yog xaiv rau cov kev xav tau ntau zog, thaum lub siab-rhiab nplaum nplaum yog siv rau kev sib txuas tsis muaj zog. Raws li kev lag luam lim tau nce siab, cov paub tab polyurethane ib leeg foaming sealing strips tau tsim, customizable nyob rau hauv cov nqe lus ntawm cov xim, ua npuas ncauj ntom, thiab nplaim kuj. Tsis tas li ntawd, cov kua nplaum gasket yog ua haujlwm rau hauv cov lim dej uas tsis muaj kev sib cais los hloov cov khoom sib khi ib txwm siv rau kev sib khi zoo. Cov kua gasket foob yog cov cuab yeej txiav-ntug thiab txhim khu kev qha qab nthab kom ua tiav qhov loj-qhov chaw ntsug laminar ntws. Nws muaj kev sib khi zoo dua li cov cuab yeej siv tshuab compression feem ntau, ua rau nws txoj kev siv dav thoob ntiaj teb. Lub sealant hauv qhov zawj yog cov kua dej uas tsis yog-Newtonian, muaj cov yam ntxwv zoo li tsis muaj hluav taws xob, roj tsis kam, acid thiab alkali tsis kam, tsis muaj tshuaj lom, thiab tsis muaj ntxhiab, nrog rau cov nplaim taws zoo, ruaj khov, thiab dielectric zog.
6. Daim ntawv thov ntawm Adhesives hauv Cua Lim- Adhesives rau Chemical Lim Ntau cov ntaub ntawv tuaj yeem siv los ua cov khoom siv adsorption rau cov tshuaj lim dej, suav nrog cov pa roj carbon activated, alumina, zeolite (molecular sieves), silica gel, ion exchange resins, thiab lwm yam. Txawm li cas los xij, cov pa roj carbon activated (xws li impregnated carbon), alumina (PIA), thiab zeolite yog cov kev xaiv nrov. Txawm hais tias siv cov khoom siv, cov tshuaj lim dej sib xyaw ua ke - muaj peev xwm adsorption. Yog li ntawd, cov nplaum xaiv yuav tsum yog ib puag ncig tus phooj ywg thiab yuav tsum tsis txhob cuam tshuam kev ua haujlwm adsorption. Adhesives kuj tuaj yeem siv los khi ntau yam khoom zoo li adsorption rau hauv cov blocks lossis ua raws li qee cov ntaub ntawv. Piv txwv li, qee qhov nyiaj ntawm cov pa roj carbon activated tuaj yeem kho ntawm ob txheej ntawm cov ntaub tsis-woven siv cov nplaum, ua kom muaj ntau hom tshuaj lim dej. Qhov no sawv cev rau qhov zoo sib xws hauv kev tsim cov tshuaj lim dej.
