Chinyorwa ichi chinonyanya kusarudza MMA, BA, AA semamonomers, uye chinokurukura zvinhu zvegraft polymerization navo, senge yekuwedzera kutevedzana, huwandu hwekuwedzera uye tembiricha yekudziya kwemutangi uye imwe neimwe monomer, uye inoona akanakisa graft polymerization process mamiriro. Iyo rubha inotanga masticated, yobva yabvongodzwa uye yakanyungudutswa nemusanganiswa wakavhengana pa70 ~ 80 ° C, uye ipapo iyo yekutanga BPO inowedzerwa mumabheti. Iyo yekutanga monomer MMA yakanyungudutswa neBOP inowedzerwa pa80 ~ 90 ° C kwemaminetsi makumi maviri, yobva yawedzerwa neyechipiri monomer yeBPO, mushure memamwe maminetsi makumi maviri, wedzera monomer yechitatu pa84 ~ 88 ℃ uye kurunga kwemaminitsi makumi mana, chengeta. inodziya kwemaawa 1.5 ~ 2, wobva watora CR/MMA-BA-AA matatu-nzira yegraft polymerization inonamira, Simba rePeel rakakura kupfuura CR/MMA-BA, kukosha kwayo i6.6 KN.m-1.
Mazwi akakosha: Neoprene adhesive, Shoe glue, Multi-component yakabatanidzwa neoprene adhesive.
Cellulose etherMCuyeHPMCkuve nekuita kwakanaka kwekupararira, emulsification, kukora, kunamatira, kuumbwa kwemafirimu, kuchengetedza mvura, uye zvakare kuve nekunyungudika kwemvura, chiitiko chepamusoro, kugadzikana, uye kunyungudika mune organic solvents.
Zvigadzirwa zvikuru zvakagadziridzwa pari zvino RT series MC uye HPMC marudzi, ane magiredhi ari 50RT (Methylcellulose), 60RT (Hydroxypropylmethylcellulose), 65RT (Hydroxypropylmethylcellulose), 75RT (Hydroxypropylmethylcellulose), inoenderana nemagiredhi eDOW A Chemical Company ari Metho, F uye K, zvichiteerana.
RT dzakatevedzana zvigadzirwa zvinobatsira zvakanyanya mukuwedzera mune zvekuvaka nekuda kwekubatana kwavo, kumiswa kugadzikana uye kuchengetedza mvura. Semuenzaniso, anogona kugadzirwa kuva emhando yepamusoro "ceramic wall uye floor tile adhesives", inowanzozivikanwa serabha poda, iyo yakashandiswa muBeijing West Railway Station, mhedzisiro yacho yakanaka. Mukuwedzera, inogona kushandiswa segelled electrolyte mu electrolytic capacitors uye bonded electrode grids mumagetsi emagetsi, seatropine, aminopyrine uye makristasi ekumashure mumishonga, uye semukobvu wemvura emulsions mumapende. Mune latex pendi uye pendi inonyungudika nemvura, inogona kushandiswa semugadziri wemufirimu-mugadziri, thickener, emulsifier uye stabilizer, nezvimwewo zvekunamatira Wallpaper, mvura rewetting rubber powder, nezvimwe.

Kuvandudzwa kwemvura-based paper plastic hand glue
Mumakore achangopfuura, nzira itsva yekunamira firimu repurasitiki pane zvakadhindwa rakagadzirwa. Iyo BOPP (biaxially oriented polypropylene firimu) yakavharwa neadhesive uye yobva yabatanidzwa pamwechete neyakadhindwa mushure mekutsikirirwa nerubha silinda uye yekudziya roller kugadzira bepa. / Purasitiki 3-mu-1 kudhindwa. Izvi zvinosanganisira dambudziko remapepa nemapurasitiki ekubatanidza. BOPP isiri-polar zvinhu, saka, pane kudiwa kwekunamira kune yakanaka kunamatira kune ese ari maviri polar uye asiri-polar zvinhu.
Kusanganisa SBS adhesive ne epoxy resin ine kuenderana kwakanaka. SBS inonzi elastomer viscose. Iyo inogona kuoneka kubva pakutadza kwayo curve kuti kuitira kukwidziridza adhesive inoparadza simba re viscose, inofanirwa kudzorwa yakatenderedza SBS: epoxy resin = 2: 1. Kubva pane peel simba curve, zvinogona kuonekwa kuti kana chiyero chakakwirira, simba repeel richava rakakura, asi kunamatira kuchawedzerawo. Kuti udzivise kunamatira, SBS: epoxy resin = 1: 1 ~ 2.5: 1 inogona kudzorwa kuti iwane zvinyoro-nyoro inokwira peel simba. Tichifunga zvakazara, sarudza iyo SBS mune guru guru: epoxy resin = 1: 1 ~ 3.5: 1.
Basa guru rekushandisa tackifying resin nderekuwedzera kusimba kwekubatanidza kwematrix uye kugadzirisa kunyorova kweglue uye nzvimbo yekubatanidza. Iyo tackifying resin inoshandiswa muchidzidzo ichi ndeye rosin tackifier inoumbwa neyakajairwa rosin uye dimerized rosin muzvikamu zvakasiyana. Kuburikidza nemiedzo yakawanda, zvinogumiswa kuti chikamu cheiyo dimerized rosin mune tackifier i22.5%, uye kusvuura simba reglue rakagadzirwa zvinoenderana nereshiyo iyi 1.59N/25mm (pepa-plastiki).
Huwandu hwetackifier hune imwe pesvedzero pane inonamatira zvivakwa. Mhedzisiro yakanakisa ndeye apo reshiyo yeguruu guru uye tackifier iri 1: 1. Peel simba N/mm epurasitiki-purasitiki 1.4, bepa-purasitiki 1.6.
Muchidzidzo ichi, MMA yakashandiswa seinonyungudutsa kusanganisa SBS neMMA. Ongororo dzakaona kuti kushandiswa kweMMA hakugone chete kuzadzisa chinangwa chekukanya zvikamu mucolloid, asi zvakare kuderedza viscosity uye kuvandudza simba rekunamatira. Naizvozvo, MMA ndiyo yakakodzera yakagadziridzwa diluent. Mushure mekuedza, huwandu hweMMA hunoshandiswa huwandu hweglue 5% ~ 10% yakakodzera.
Sezvo viscose yakagadzirwa inofanira kunge yakanyungudika mumvura, tinosarudza white latex (polyvinyl acetate emulsion) semutakuri wemvura. Kuwanda kwewhite latex kunotora 60% yeviscose yose. Mushure mokunge mvura-based viscose yakasvibiswa mumvura-emulsion state kuburikidza nekupararira uye emulsification yemutakuri we emulsified, kana kusanganiswa kwayo kwakasvibiswa kusina kukodzera kushandiswa, kunogona kuderedzwa nemvura. Iyi dilution nzira ndeyese inodhura-yakaderera uye isiri-chepfu (hapana chikonzero chekushandisa organic zvinonyungudutsa), uye yakanakisa mhando yemvura yekunyungudutsa i10% ~ 20%.
Kuti ubvise zvakasara zve viscose, inoedzwa kuti dilute Na2CO3 solution inoshandiswa sealkalizing agent, uye mhedzisiro yacho ndiyo yakanyanya kunaka. Dzidziso yemhedzisiro yealkalizing agent inogona kunge iri yekuti saponification reaction inounza mamwe maion akasimba epolar, senge sodium ion, zvekuti iyo yekutanga insoluble rosin acid inoshandurwa kuita Soluble sodium munyu. Mukuwedzera, kana chigadziko chakanyanya chakasimba chakawedzerwa kune glue, simba rekunamatira richarasika, kuitira kuti glue rikundike, saka glue haina kukodzera kune alkaline environment.
Kuyerera kwakakodzera kwemaitiro.
