Eli nqaku ikakhulu likhetha i-MMA, BA, AA njenge-monomers, kwaye lixoxa ngemiba yokugxunyekwa kwepolymerization kunye nabo, njengolandelelwano lokudibanisa, isixa sokongeza kunye nobushushu bokusabela komqalisi kunye ne-monomer nganye, kwaye ifumanisa ezona meko zilungileyo zenkqubo ye-graft polymerization. I-rubber iqala ukuhlanjululwa, emva koko ixutywe kwaye ichithwe nge-solvent exutywe kwi-70 ~ 80 ° C, kwaye i-initiator BPO yongezwa kwiibhetshi. I-monomer yokuqala ye-MMA enyibilikisiweyo nge-BOP yongezwa kwi-80 ~ 90 ° C imizuzu engama-20, kwaye yongezwa nge-monomer yesibini ye-BPO, emva kwenye imizuzu engama-20, yongeza i-monomer yesithathu kwi-84 ~ 88 ℃ kwaye ivuselele imizuzu engama-45, gcina. shushu iiyure eziyi-1.5 ~ 2, emva koko ufumane i-CR/MMA-BA-AA indlela emithathu yokuncamathelisa i-polymerization, amandla ePeel makhulu kune CR/MMA-BA, ixabiso layo 6.6 KN.m-1.
Amagama angundoqo: I-Neoprene encamathelayo, iglu yeZihlangu, i-Multi-component encamatheleyo neoprene.
Iselulosi etherMCkwayeHPMCukusebenza kakuhle kwe-dispersion, i-emulsification, ukuqina, ukunamathela, ukubunjwa kwefilimu, ukugcinwa kwamanzi, kunye nokuba ne-solubility egqwesileyo yamanzi, umsebenzi ongaphezulu, ukuzinza, kunye nokunyibilika kwizinyibilikisi ze-organic.
Iimveliso eziphambili eziphuhliswayo ngoku ziyi-RT series MC kunye neentlobo ze-HPMC, ezinamabakala angama-50RT (Methylcellulose), 60RT (Hydroxypropylmethylcellulose), 65RT (Hydroxypropylmethylcellulose), 75RT (Hydroxypropylmethylcellulose), ehambelana namabakala e-DOW A Chemical Company, i-Metho F kunye no-K, ngokulandelelanayo.
Iimveliso ze-RT zechungechunge ziluncedo kakhulu kwizinto zokwakha ngenxa yokubambisana kwazo, ukuzinza kokumiswa kunye nokugcinwa kwamanzi. Ngokomzekelo, zinokuthi zenziwe ngekhwalithi ephezulu "yodonga lwe-ceramic kunye ne-adhesive tile floor", eyaziwa ngokuba yi-rubber powder, esetyenziswe kwiSitishi sikaloliwe saseBeijing eNtshona, umphumo ulungile. Ukongezelela, ingasetyenziselwa njenge-electrolyte edibeneyo kwi-electrolytic capacitors kunye neegridi ze-electrode eziboshiweyo kwizixhobo zombane, njenge-atropine, i-aminopyrine kunye ne-crystals anal kwi-pharmaceuticals, kunye ne-thickener ye-emulsions yamanzi kwiipende. Kwipeyinti ye-latex kunye nepeyinti e-soluble yamanzi, ingasetyenziselwa njenge-agent-forming agent, i-thickener, i-emulsifier kunye ne-stabilizer, njl. Ukunamathela kwi-wallpaper, ukumanzisa irabha powder, njl.
Amagama angundoqo: I-Methyl Cellulose, i-Hydroxy Propyl Cellulose, i-adhesive, isicelo.
Ukuphuhliswa kweglue yesandla seplastiki esekelwe ngamanzi
Kwiminyaka yakutshanje, inkqubo entsha yokuncamathisela ifilimu yeplastiki kwizinto eziprintiweyo iye yaphuhliswa. I-BOPP (ifilimu ye-polypropylene e-biaxially oriented oriented) idityaniswe nge-adhesive kwaye idityaniswe kunye nento eprintiweyo emva kokuba icinezelwe nge-cylinder yerabha kunye ne-roller yokufudumeza ukwenza iphepha. / Iplastiki 3-in-1 print. Oku kubandakanya ingxaki yokudibanisa iphepha kunye neplastiki. I-BOPP yinto engeyiyo i-polar, ngoko ke, kukho imfuneko ye-adhesive ene-adhesion efanelekileyo kwizinto zombini kunye ne-polar.
Ukuxuba i-adhesive ye-SBS kunye ne-epoxy resin inokuhambelana kakuhle. I-SBS yi-viscose ye-elastomer. Inokubonwa kwigophe layo lokungaphumeleli ukuba ukwenzela ukuba kulungiswe amandla okutshabalalisa okunamathelayo kwe-viscose, kufuneka ilawulwe malunga ne-SBS: i-epoxy resin = 2: 1. Ukusuka kwi-curve yamandla e-peel, kunokubonwa ukuba xa umlinganiselo uphezulu, amandla e-peel aya kuba mkhulu, kodwa ukunamathela kuya kwanda. Ukuze ugweme ukunamathela, i-SBS: i-epoxy resin = 1: 1 ~ 2.5: 1 inokulawulwa ukuze ifumane amandla e-peel akhuphuka ngobumnene. Ukuqwalasela ngokubanzi, misela i-SBS kwi-glue ephambili: i-epoxy resin = 1: 1 ~ 3.5: 1.
Umsebenzi oyintloko wokusebenzisa i-tackifying resin kukwandisa amandla okubambisana kwe-matrix kunye nokuphucula ukumanzisa kweglue kunye ne-bonding surface. I-resin tackifying esetyenziswe kolu phando yi-rosin tackifier eyenziwe nge-rosin eqhelekileyo kunye ne-rosin edibeneyo ngokwemilinganiselo eyahlukeneyo. Ngokusebenzisa iimvavanyo ezininzi, kugqitywa ukuba ipesenti ye-rosin e-dimerized kwi-tackifier yi-22.5%, kwaye amandla e-peelling yeglue elungiselelwe ngokwalo mlinganiso ngu-1.59N / 25mm (iphepha-plastiki).
Umthamo we-tackifier unempembelelo ethile kwiipropati zokubambelela. Isiphumo esihle kakhulu xa umlinganiselo weglue oyintloko kunye ne-tackifier yi-1: 1. Amandla e-Peel N / mm iplastiki-iplastiki 1.4, iphepha-iplastiki 1.6.
Kolu phononongo, i-MMA isetyenziswe njenge-diluent ukudibanisa i-SBS kunye ne-MMA. Iimvavanyo ziye zafumanisa ukuba ukusetyenziswa kwe-MMA akukwazi ukufezekisa injongo yokuxubha amacandelo kwi-colloid, kodwa nokunciphisa i-viscosity kunye nokuphucula amandla okubambelela. Ke ngoko, i-MMA yidiluent elungisiweyo efanelekileyo. Emva kovavanyo, inani le-MMA elisetyenzisiweyo lilonke inani leglue 5% ~ 10% lifanelekile.
Ekubeni i-viscose eyenziweyo kufuneka ibe yi-soluble yamanzi, sikhetha i-latex emhlophe (i-polyvinyl acetate emulsion) njenge-carrier-soluble carrier. Isixa se-latex emhlophe senza i-60% ye-viscose iyonke. Emva kokuba i-viscose esekelwe emanzini ifakwe kwi-emulsion state ngokusebenzisa ukusabalalisa kunye ne-emulsification ye-carrier emulsified, ukuba ukulungelelaniswa kwayo okuhlanjululwayo akufanelekile ukusetyenziswa, kunokuhlanjululwa ngamanzi. Le ndlela yokuhlanjululwa inexabiso eliphantsi kwaye ayinayo ityhefu (akukho mfuneko yokusebenzisa izinyibilikisi eziphilayo), kwaye uluhlu olungcono lwamanzi okuhlamba yi-10% ~ 20%.
Ukuze ususe intsalela ye-viscose, kuvavanywa ukuba i-dilute ye-Na2CO3 isisombululo isetyenziswe njenge-alkalizing agent, kwaye umphumo ungcono kakhulu. Ithiyori yempembelelo ye-alkalizing agent inokuthi i-saponification reaction ivelise i-ion eqinile ye-polar, efana ne-sodium ion, ukuze i-asidi ye-rosin enganyibilikiyo iguqulwe ibe yityuwa yesodium enyibilikayo. Ukongezelela, ukuba isiseko esinamandla kakhulu songezwa kwi-glue, i-adhesive force iya kulahleka, ukwenzela ukuba i-glue iphumelele, ngoko iglue ayifanelekanga kwindawo ye-alkaline.
Ukuhamba kwenkqubo efanelekileyo.
