Hydroxyethyl Cellulose (HEC) ni ionic ionic water-soluble polymer compound imiterere yimiti ihindurwa kuva selile ikoresheje hydroxyethylation reaction. HEC ifite amazi meza, kubyimba, guhagarika, kwigana, gukwirakwiza no gukora firime, bityo ikoreshwa cyane mubikoresho byubaka, gutwikira, imiti ya buri munsi ninganda zikora ibiribwa. Muri spray-coated yihuta-gushiraho reberi asifalt idafite amazi, kwinjiza hydroxyethyl selulose birashobora kunoza cyane ubushyuhe bwayo.
1. Ibintu shingiro bya hydroxyethyl selulose
Hydroxyethylcellulose ifite ubushobozi bwo kubyimba no gukora firime mumazi, bigatuma iba umubyimba mwiza kubwoko butandukanye bushingiye kumazi. Yongera cyane ubwiza bwirangi mugukora imigozi ya hydrogène hamwe na molekile zamazi, bigatuma urusobe rwa molekile zamazi zikomera. Uyu mutungo ni ingenzi cyane mu gutwikira amazi, kubera ko ubukonje bwinshi bufasha igifuniko kugumana imiterere n'ubunini mbere yo gukira, bigatuma firime ihoraho kandi ikomeza.
2. Uburyo bwo kunoza ubushyuhe
2.1 Ongera ituze ryimyenda
Kubaho hydroxyethyl selulose irashobora kuzamura ubushyuhe bwumuriro wa rubber asfalt. Ubukonje bwamabara buragabanuka mugihe ubushyuhe buzamutse, kandi hydroxyethyl selulose itinda iki gikorwa kandi ikagumana imiterere yumubiri. Ni ukubera ko itsinda rya hydroxyethyl muri molekile ya HEC rishobora gukora umuyoboro uhuza umubiri hamwe nibindi bice bigize igifuniko, ibyo bikaba byongera ubushyuhe bwumuriro wa firime ya coating kandi bikabasha gukomeza imiterere myiza nimikorere mugihe cy'ubushyuhe bwinshi.
2.2 Kunoza imiterere yubukanishi bwa firime
Imiterere yubukorikori bwa firime yo gutwikira, nkubworoherane, imbaraga zingana, nibindi, bigira ingaruka kumikorere yabyo mugihe cy'ubushyuhe bwinshi. Itangizwa rya HEC rishobora kuzamura imiterere yubukorikori bwa firime ya coating, biterwa ahanini ningaruka zayo zibyibushye bituma firime ya coating iba denser. Imiterere ya firime yuzuye ntabwo yongerera imbaraga ubushyuhe gusa, ahubwo inongerera ubushobozi bwo kurwanya imihangayiko yumubiri iterwa no kwaguka kwinshi nubushyuhe bwo hanze, bikarinda kumeneka cyangwa gukuramo firime.
2.3 Kuzamura ifatizo rya firime
Mugihe cy'ubushyuhe bwo hejuru, impuzu zidafite amazi zikunda gusibanganya cyangwa gukuramo, ibyo biterwa ahanini no kudahuza bihagije hagati ya substrate na firime. HEC irashobora kunonosora igifuniko cya substrate mugutezimbere imikorere yubwubatsi hamwe nibikorwa bya firime. Ibi bifasha igifuniko gukomeza guhuza hafi na substrate mubushyuhe bwinshi, bikagabanya ibyago byo gukuramo cyangwa gusibanganya.
3. Amakuru yubushakashatsi hamwe nibikorwa bifatika
3.1 Igishushanyo mbonera
Kugirango hamenyekane ingaruka za hydroxyethyl selulose kumurwanya wubushyuhe bwatewe na rubber asfalt yihuta yangiza amazi, hashobora gukorwa ubushakashatsi. Mu bushakashatsi, ibintu bitandukanye bya HEC birashobora kongerwaho kubutaka butarimo amazi, hanyuma ubushyuhe bwumuriro, imiterere yubukanishi hamwe no gufatira kuri coating birashobora gusuzumwa hifashishijwe isesengura rya thermogravimetric (TGA), isesengura rinini rya mikorobe (DMA) hamwe no gupima ibintu.
3.2 Ibisubizo byubushakashatsi
Ibisubizo byubushakashatsi byerekana ko nyuma yo kongeramo HEC, ubushyuhe bwihanganira ubushyuhe bwa coating bwiyongereye cyane. Mu itsinda rishinzwe kugenzura nta HEC, firime yatwikiriye yatangiye kubora kuri 150 ° C. Nyuma yo kongeramo HEC, ubushyuhe firime yatwikiriye yashoboraga kwiyongera hejuru ya 180 ° C. Byongeye kandi, itangizwa rya HEC ryongereye imbaraga zingana na firime ya coating hafi 20%, mugihe ibizamini byo gukuramo byerekanaga ko gufatira kuri substrate kwiyongera hafi 15%.
4. Porogaramu yubuhanga no kwirinda
4.1
Mubikorwa bifatika, ikoreshwa rya hydroxyethyl selulose irashobora kunoza cyane imikorere yubwubatsi nigikorwa cyanyuma cyo gutera vuba vuba reberi ya asfalt yangiza amazi. Ipitingi yahinduwe irashobora gukoreshwa mumirima nko kubaka amazi, kutubaka amazi yo munsi yubutaka, hamwe na anticorrosion ya pipine, kandi birakwiriye cyane cyane kubisabwa n’amazi mu bushyuhe bwo hejuru.
4.2
Nubwo HEC ishobora kunoza imikorere yimyenda, dosiye yayo igomba kugenzurwa neza. HEC ikabije irashobora gutuma ubwiza bwikibiriti buba hejuru cyane, bikagira ingaruka kubikorwa byubwubatsi. Kubwibyo, muburyo bwa formulaire, dosiye ya HEC igomba gutezimbere binyuze mubigeragezo kugirango igere kubikorwa byiza byo gutwikira no kubaka.
Hydroxyethyl selulose itezimbere neza ubushyuhe bwokwirinda ubushyuhe bwihuse bwa reberi ya asfalt yihuta yamazi yongerewe ubwiza bwikibiriti, ikazamura imiterere yubukorikori bwa firime, kandi ikanoza neza. Ubushakashatsi bwakozwe hamwe nibikorwa bifatika byerekana ko HEC igira ingaruka zikomeye mugutezimbere ubushyuhe bwumuriro no kwizerwa. Gukoresha mu buryo bushyize mu gaciro HEC ntibishobora kongera imikorere yubwubatsi gusa, ariko kandi byongerera cyane igihe cyigihe cyigihe cyo gutwika amazi atagira amazi ahantu hashyuha cyane, bitanga ibitekerezo nuburyo bushya bwo guteza imbere ibikoresho byubaka amazi.
