1. Iimpawu ze-TPEband ukumelana
Isixhobo se-TPE sinokomelela okuhle kunye namandla okuqina, kwaye siziva sikhululekile kwaye sigudile.Ikhutshwe ngokuthe ngqo kwaye yenziwe yi-extruder, kwaye ukulungiswa kulula kwaye kulula.I-TPE inoxhathiso olulambathayo lweoyile.I-TPE ivutha ngevumba elibi, kwaye umsi mncinci kwaye ukhaphukhaphu.
Izinto ze-TPE zixutywe izinto ezilungisiweyo, kwaye iimpawu zayo ezibonakalayo zinokuhlengahlengiswa okuninzi, kwaye ubunzima obuthile buphakathi kwe-0.89 kunye ne-1.3.Ubunzima buqhele ukuba phakathi kwe28A-35A Shore.Ubunzima obuphezulu okanye obuphantsi kakhulu buya kuchaphazela ukusebenza kweband ukumelana.
I-TPEband ukumelana izinto zisebenzisa i-SEBS njengeyona nto iphambili.I-SEBS ikwayinto ehambelana nokusingqongileyo ehlangabezana nomgangatho we-REACH, ngoko ke ayizukubangela kuchaphazeleka kwamaqela akhethekileyo.Ibhanti elilastiki elenziwe nge-TPE linomphezulu ogudileyo, akukho masuntswana kunye nezinto zangaphandle, kwaye lisagcina i-elasticity egqwesileyo kwindawo yobushushu obuphantsi ngaphandle kobunzima kunye ne-brittle.Ukuchasana kwemozulu okugqwesileyo, kunokusetyenziswa kwindawo ye-40-90 degrees Celsius, kwaye akuyi kuba nokuqhekeka kusetyenziso lwangaphandle ngaphakathi kolu luhlu lobushushu.
Izinto eziphambili ezisetyenziswe kwi-TPE, i-SEBS, iqulethe inani elikhulu le-butadiene, eneempawu zomlinganiselo ophezulu wokwelula kunye ne-deformation encinci.Sivavanye ukuba ukolula amaxesha angama-3 ngaphezulu kwamaxesha angama-30,000 kuya kubangela ukuguqulwa okuncinci, kodwa kungabi ngaphezulu kwe-5%.
2. Iimpawu zelatexband ukumelana
ILatex inokumelana nokunxiba okufanelekileyo, ukumelana nobushushu, ukuqina okuphezulu, ukomelela kokukrazula kunye nobude ngaphezu kwamaxesha asi-7.Kulula ukuguga emoyeni, mhlophe xa utshiza iqabaka.Ngenxa yobukho beemolekyuli zeprotheyini ezingafaniyo kwi-latex yendalo, inokubangela ukuchasana kwabantu abathile.
I-latex yendalo inqunywe kumthi werabha.Luhlobo lwerabha yendalo.Ilulwelo, imhlophe qhwa, kwaye ayinancasa.Ilatex yendalo entsha iqulethe i-27% ukuya kwi-41.3% yerabha, i-44% ukuya kwi-70% yamanzi, i-0.2% ukuya kwi-4.5% yeprotheyini, i-2% ukuya kwi-5% yentlaka yendalo, i-0.36% ukuya kwi-4.2% yeswekile, kunye ne-0.4% ye uthuthu.Ukuze kuthintelwe i-latex yendalo ukuba idibanise ngenxa ye-microorganisms yayo kunye ne-enzymes, i-ammonia kunye nezinye izizinzi zeekhemikhali zihlala zongezwa.
Risistance band I-latex ingcono okanye i-tpe ingcono, zombini zineenzuzo kunye nokungalungi.Isetyenziswa kwintsimi yeband ukumelanas, ukhetho lwezinto ze-TPE lukwazi ngokupheleleyo ukusebenza kwalo, kwaye ixabiso liphantsi.Ukuthelekisa ezi zinto zimbini, akukho nto ilungileyo okanye imbi.Kusafuneka senze isigqibo ngokwentsebenzo kunye neemfuno zesicelo semveliso.
2. Umahluko phakathi kweTPUband ukumelana kunye ne-TPEband ukumelana
Nangona i-TPU kunye ne-TPE zingumahluko weleta, ukusetyenziswa kwe-TPUband ukumelana kunye ne-TPEband ukumelana yahluke kakhulu.Umfanekiso omncinci weTPUband ukumelana ikhanya kwintsimi yeengubo eziphothiweyo, ezifana nekhola kunye ne-cuffs yeengubo eziphothiweyo, i-shoulder seam kunye ne-side seams.Yintoni i-TPE elasticity eyithathayo kukuba indlela yamandla inesimo esithile kwisixhobo sokuqina komzimba, esifana nokomelelaband ukumelanas, izixhobo zokufaneleka iibhendi zoxinzelelo njalo njalo.Nokuba yi-TPUband ukumelana okanye TPEband ukumelana, aziyikhathalelanga imeko-bume yaye zihlala ixesha elide.Owona mahluko usisiseko phakathi kwabo ngumahluko kububanzi bembonakalo kunye nobukhulu kunye nobubanzi bokusetyenziswa.Kakade ke, izinto ekrwada nazo zahluke kancinane.
1. Umahluko kwimbonakalo kunye nobungakanani bokusetyenziswa
Umbala we-TPUband ukumelana iqabaka ecacileyo, ngokubanzi ububanzi buphakathi kwe-2MM kunye ne-30MM, kwaye ubukhulu buphakathi kwe-0.08MM kunye ne-1MM.Isetyenziswe kwikhola kunye neengubo zeengubo eziboyiweyo, kwaye i-shoulder seam side seams yenziwe ukuba inike umphumo omuhle ongabonakaliyo.Akukho mfuneko yokuqwalasela ukuhambelana kombala;ububanzi bayo ngokuqhelekileyo bufana nobubanzi bemibhobho, okwenza kube lula ukufihla ibhanti;ubukhulu obuncinci abuyi kuchaphazela intuthuzelo yeengubo ezinithiweyo emva kokuthunga.
Umbala we-TPEband ukumelana yahlukene ngakumbi, njengombala wendalo, oblowu, omthubi, oluhlaza, obomvu, o-orenji, opinki, omfusa, njl njl. ., Imibala iyahluka kwaye ilungele ukuba abasebenzisi bakhethe.Ngenxa yokuba i-TPEband ukumelana ibanzi kwaye ijiyile, inokumelana noxinzelelo olungcono kwaye ilungele ukusetyenziswa kwizixhobo zokuzilolonga.
2. Umahluko phakathi kwemathiriyeli ekrwada
Zombini i-TPU kunye ne-TPE zizinto ze-thermoplastic ezine-elasticity yerabha, kwaye zombini zinerabha elungileyo.Xa kuthelekiswa, i-TPE igqwesile ngakumbi ngokwemiqathango yokuthuthuzela okuchukunyiswayo, kwaye i-TPU inokuqina okugqwesileyo kunye namandla.Kunzima ukwahlula phakathi kwe-TPE kunye ne-TPU ngokujonga okubonakalayo kuphela.Qala ngeenkcukacha ukuhlalutya umahluko kunye nomahluko phakathi kweTPE kunye neTPU:
I-1) Ukucaca kwe-TPU kungcono kune-TPE, kwaye akulula ukunamathela njenge-TPE ecacileyo;
I-2) Ubunzima obuthile be-TPU buhluka ngokubanzi, ukusuka kwi-1.0 ukuya kwi-1.4, ngelixa i-TPE iphakathi kwe-0.89 ukuya kwi-1.3, ngokukodwa kwindlela yokudibanisa, ngoko ke ubunzima obuthile buguquka kakhulu;
3) I-TPU inokumelana ne-oyile engcono, ngelixa i-TPE inokumelana ne-oyile ephantsi;
I-4) I-TPU iyatshisa ngephunga elikhanyayo, kunye nomsi omncinci kunye nokukhanya, kwaye kukho isandi esincinci sokuqhuma xa sitshisa, i-TPE inephunga elimnandi xa livutha, kwaye umsi uncinci kwaye ulula;
I-5) Ukuqina kwe-TPU kunye nokusebenza kwe-elastic recovery kungcono kune-TPE;
6) Ukumelana nokushisa kwe-TPU yi-60 degrees Celsius ukuya kuma-80 degrees Celsius, i-TPE yi-60 degrees Celsius ukuya kwi-105 degrees Celsius;
I-7) Ngokubhekiselele kwimbonakalo kunye nokuziva, kwiimveliso ezithile ezigqithisiweyo, iimveliso ze-TPU zinemvakalelo enzima kunye nokuxhatshazwa okunamandla kuneemveliso ze-TPE;ngelixa iimveliso ze-TPE zinemvakalelo ethambileyo kunye nethambileyo kunye nokusebenza okubuthathaka.
Ngokubanzi, iTPUband ukumelana iyabonakala kwaye ineqabaka, ilula kwaye ithambile, inokomelela kakuhle, iqinile, kwaye akukho lula ukuyiqhawula.Ifanelekile kwi-knitwear collar cuff hemming kunye ne-shoulder seam side seam seam.I-TPEband ukumelana inemibala eyahluka-hlukeneyo, ikhululekile xa iphathwa, inomlinganiselo ophezulu wokolula, kwaye inokomelela okugqwesileyo.Ifanelekile ukusetyenziswa kwizixhobo zokufaneleka.
