Iyi ngingo ihitamo cyane cyane MMA, BA, AA nka monomers, ikanaganira ku mpamvu ziterwa na polimerisiyoneri hamwe nazo, nk'urutonde rwongeweho, umubare wongeyeho n'ubushyuhe bwa reaction ya nyirubwite na buri monomer, ikanamenya uburyo bwiza bwo gutunganya polymerisation. Rubber yabanje gukonjeshwa, hanyuma ikavangwa hanyuma igashonga hamwe na solide ivanze kuri 70 ~ 80 ° C, hanyuma uwatangije BPO akongerwaho mubice. Monomer ya mbere MMA yasheshwe na BOP yongewe kuri 80 ~ 90 ° C muminota 20, hanyuma ikongerwamo na monomer ya kabiri ya BPO, nyuma yiminota 20, ongeramo monomer ya gatatu kuri 84 ~ 88 ℃ hanyuma ukangure muminota 45, komeza shyushye kumasaha 1.5 ~ 2, hanyuma ubone CR / MMA-BA-AA uburyo butatu bwa graft polymerisation yometseho, Imbaraga za Peel ziruta CR / MMA-BA, agaciro kayo ni 6.6 KN.m-1.
Amagambo shingiro: Ibiti bya Neoprene, kole yinkweto, Ibice byinshi byashizwemo na neoprene.
Cellulose etherMCnaHPMCKugira imikorere myiza yo gutatanya, emulisiyasi, kubyimba, gufatira hamwe, gukora firime, kubika amazi, kandi ikagira kandi amazi meza cyane, ibikorwa byubutaka, ituze, hamwe no gushonga mumashanyarazi.
Ibicuruzwa byingenzi byatejwe imbere ubu ni ubwoko bwa RT MC na HPMC, amanota yabo ni 50RT (Methylcellulose), 60RT (Hydroxypropylmethylcellulose), 65RT (Hydroxypropylmethylcellulose), 75RT (Hydroxypropylmethylcellulose), ihuye n amanota ya DOW Chemical Company, Methocel A Methocel. F na K.
Ibicuruzwa bya seriveri ya RT nibyingenzi byongewe mubikoresho byubaka kubera guhuriza hamwe, guhagarara neza no gufata amazi. Kurugero, zirashobora guhindurwa muburyo bwiza cyane "urukuta rwa ceramic na etage ya tile yometseho", bakunze kwita ifu ya rubber, yakoreshejwe muri gari ya moshi ya Beijing, ingaruka ni nziza. Byongeye kandi, irashobora gukoreshwa nka electrolyte ikonjeshejwe muri capacitori ya electrolytike hamwe na gride ya electrode ihujwe mubikoresho byamashanyarazi, nka atropine, aminopyrine na kristu ya anal muri farumasi, kandi nkibyimbye kugirango emulisiyo yamazi irangi. Mu irangi rya latex hamwe no gusiga irangi ryamazi, birashobora gukoreshwa nkibikorwa byo gukora firime, kubyimbye, emulisiferi na stabilisateur, nibindi kugirango bifatanye na wallpaper, amazi asubiramo ifu ya reberi, nibindi.
Amagambo shingiro: Methyl Cellulose, Hydroxy Propyl Cellulose, ifata, ikoreshwa.
Gutezimbere amazi ashingiye kumpapuro
Mu myaka yashize, hashyizweho uburyo bushya bwo gushira firime ya plastike ku bintu byacapwe. Ni BOPP (firime ya polypropilene yerekanwe na biaxial) yometseho ibifunga hanyuma igahuzwa hamwe nibintu byacapwe nyuma yo gukanda kuri silinderi ya reberi hamwe na roller yo gushyushya kugirango ikore impapuro. / Plastike 3-muri-1 Icapa. Ibi birimo ikibazo cyimpapuro no guhuza plastike. BOPP ni ibikoresho bidafite inkingi, kubwibyo, hakenewe ibifatika bifatanye neza nibintu byombi cyangwa bitari polar.
Kuvanga SBS yifatanije na epoxy resin ifite guhuza neza. SBS ni viscose ya elastomer. Birashobora kugaragara uhereye kunanirwa kwayo ko kugirango uhindure imbaraga zangiza zangiza za viscose, zigomba kugenzurwa hafi ya SBS: epoxy resin = 2: 1. Uhereye ku mbaraga zishishwa zumurongo, birashobora kugaragara ko mugihe igipimo kiri hejuru, imbaraga zishishwa zizaba nini, ariko gufatira hamwe nabyo biziyongera. Kugirango wirinde gufatana, SBS: epoxy resin = 1: 1 ~ 2.5: 1 irashobora kugenzurwa kugirango ubone imbaraga zizamuka buhoro buhoro. Urebye neza, menya SBS muri kole nkuru: epoxy resin = 1: 1 ~ 3.5: 1.
Igikorwa nyamukuru cyo gukoresha tacking resin ni ukongera imbaraga zo guhuza matrix no kunoza ubuhehere bwa kole hamwe nubuso buhuza. Gukoresha resin ikoreshwa muri ubu bushakashatsi ni rosin tackifier igizwe na rosine isanzwe hamwe na rozine dimerized muburyo butandukanye. Binyuze mu bizamini byinshi, hanzuwe ko ijanisha rya rosin dimerized muri tackifier ari 22.5%, naho imbaraga zo gukuramo kole zateguwe ukurikije iki kigereranyo ni 1.59N / 25mm (impapuro-plastike).
Ingano ya tackifier igira ingaruka runaka kumiterere. Ingaruka nziza nigihe igipimo cya kole nyamukuru na tackifier ari 1: 1. Imbaraga zishishwa N / mm plastike-plastike 1.4, impapuro-plastike 1.6.
Muri ubu bushakashatsi, MMA yakoreshejwe nka diluent yo guhuza SBS na MMA. Ubushakashatsi bwerekanye ko ikoreshwa rya MMA ridashobora kugera gusa ku ntego yo guteka ibice muri koleo, ahubwo binagabanya ubukonje no kunoza imbaraga zifatika. Kubwibyo, MMA nikintu cyahinduwe gikwiye. Nyuma yubushakashatsi, ingano ya MMA yakoreshejwe nigiteranyo cya kole 5% ~ 10% birakwiye.
Kubera ko viscose yateguwe igomba kuba ibora amazi, duhitamo latx yera (polyvinyl acetate emulsion) nkikwirakwiza amazi. Ingano ya latex yera igera kuri 60% ya viscose yose. Nyuma ya viscose ishingiye kumazi yatewe mumazi-emulisiyoneri binyuze mu gutatanya no kwigana kwa nyirubwite, niba ihindagurika ryayo ridakwiriye gukoreshwa, irashobora kuvangwa n'amazi. Ubu buryo bwa dilution bwaba buhendutse kandi butari uburozi (nta mpamvu yo gukoresha ibishishwa kama), kandi amazi meza yo kwisuka ni 10% ~ 20%.
Kugirango ukureho ibisigisigi bya viscose, hapimwa ko umuti wa Na2CO3 ukoreshwa nkumuti wa alkalizing, kandi ingaruka nibyiza. Igitekerezo cyingaruka ziterwa na alkalizing agent gishobora kuba uko reaction ya saponification itangiza ion zikomeye za polar, nka sodium ion, kuburyo aside ya rosine yumwimerere idashobora guhinduka ihinduka umunyu wa sodium ya Soluble. Byongeye kandi, niba ifatizo rikomeye cyane ryongewe kuri kole, imbaraga zifatika zizabura, kugirango kole yananirwe, bityo kole ntikwiriye ibidukikije bya alkaline.
Inzira ikwiye.
