Kushandiswa kwePUR Hot Melt Adhesive: Textile

Nekushandiswa kwezvinonamira zvinopisa zvinonyunguduka uye tekinoroji yavo yekubatanidza muindasitiri yemachira, tekinoroji yekusona yemicheka nemachira yakatsiviwa nehunyanzvi hwekubatanidza, nekudaro kuchengetedza machira neshinda yekusonesa uye kuwedzera kugona kwekugadzira. Mumakore achangopfuura, PUR inopisa melt adhesives yakashandiswawo muhuwandu mukugadzira machira asina kuruka. PUR inopisa inonyunguduka inonamira inoshandiswa zvakanyanya sembatya, zvinhu zvekurapa, sefa zvinhu, machira ekupukuta, machira echisvusvuro, magumbeze, matehwe ekugadzira, machira ekudzivirira, nezvimwe.

Iyo huru inonamira yemachira maapplication ndeyePUR inopisa inonyungudika inonamatira. Iko kushandiswa kwePUR inopisa melt adhesives inofanira kutanga yatora nhoroondo yakazara yezvivakwa uye maitiro emucheka wefiber. Pamusoro peiyo yekubatanidza zvinhu zvePUR inopisa melt adhesives ivo pachavo, zvinonyanya kukosha kufunga nezve washability uye kupihwa kwemafibhi. Inowanzo shandiswa PUR inopisa inonyunguduka adhesive ye polyamide faibha, polyester fiber, makushe uye mamwe machira haana kunaka akakwana bonding performance. Kuti ugadzirise uye uenderane nezvinodiwa zvejira, kazhinji shandisa tetrachlorethylene, trichlorethylene uye mamwe chlorinated hydrocarbon solvents uye turpentine sezvinonyungudutsa, uye zvakare kuvandudza ayo agglutination simba anogona zvakare kushandisa yakanaka yakaoma kuchenesa inopikisa polima, senge copolymer. nylon, polyurethane uye zvimwe zvinonamira zvehwaro zvinhu.

Kunyanya kune zvekugadzira fibers, nekuda kwekukanganisa kwavo senge nyore kushanduka, kunyunguduka, shrinkage uye kuoma kwemaoko kunzwa kana kupisa, iyo inonamira inodiwa kuve nekumwe kusamira kwemvura, kupisa kwakanyanya, uye kusapikisa kupisa uye chiedza. Yellowing uye isina-discoloring, rudzi urwu rwekunamatira inodawo shoma dosage, high adhesion, yakanaka operability uye processing performance, etc. PUR inopisa melt adhesive ine maitiro ari pamusoro apa. Kuti uwane mhedzisiro inogutsa yekubatanidza, matanho akasiyana anotorwa kune akasiyana bonding media. Semuenzaniso, kupisa kwekudzivirira kweacrylonitrile fiber uye acetate fiber i80 ~ 120â, kupisa kwekushisa kwePP fiber, nylon uye polyester fiber ndeye 160 ~ 180â, uye kupisa kwekushisa kwekotoni uye yerineni yepakati inowanzo. 180~200â. Paunenge uchishandisa hot melt adhesive, zvinodikanwa kuchengetedza fluidity pane imwe tembiricha yakafanana. Kunyangwe tembiricha yakadzikira, kunyangwe paine fluidity, zviri nyore kudzikisa simba rekunamatira uye kupisa kupisa kwekunamatira. Iyo copolymer nylon (nylon 12) inogona kuderedza kupfava poindi, asi zvakare inogona kuvandudza kunamatira, ine yakanaka kunamatira kunenge zvese zvinhu.

Iyo inopisa-yakanyunguduka yekunamira tekinoroji iyo yakashandiswa muzvigadzirwa zvemachira efayibha kazhinji inonamira yakasimba yakagadzirwa ne thermoplastic polymer seyakadzika zvinhu uye yakanyungudika-yakasanganiswa ne tackifier, plasticizer uye antioxidant. , isina zvinonyungudutsa uye unyoro. Naizvozvo, hapana chikonzero chekuomesa midziyo uye nguva yekuomesa, ingoisa iyo inonamira nemushini wekupfekedza uye woimanikidza kuti ipedze kusungirira.

Kana iwe ukasangana nekupisa kunyunguduka adhesive permeability hakushande, ipapo mhando yekupisa inonyungudika yakanamatira pamubvunzo wemubvunzo. Isu tinokurudzira kuti iwe unofanirwa kupa pamberi kune yakanaka qualifications, nguva uye ruzivo rweanopisa anonyunguduka adhesive vanogadzira inopisa melt adhesive research nekusimudzira, timu yekuongorora mhando yakakoshawo, uye isuPurkingmuChina, iyo inopisa inonyunguduka inonamira isu tinoziva zviri nani uye inopa mhinduro.Bata nesu izvozvikuziva yedu inopisa inonyunguduka inonamira nyaya uye kudzidza nezve inopisa inonyungudutsa adhesive application,Customizeiyo yakanyanya kunaka uye inonyanya kushanda uye inonamira yakanakira iwe!
