RDP yo kurukuta
IsubirwamoIfu ya polymer RDP / VAE, ni ifu idasanzwe ya emulsion spray yumye ikozwe muri Ethylene na vinyl acetate copolymer, kubera ubushobozi bwayo bwo guhuza hamwe nibintu byihariye, nka: kurwanya amazi, kubaka no kubika ubushyuhe, kubwibyo, bifite uburyo bwinshi bwo gukoresha.
Ni uruhe ruhare ya RDPirashobora gukinaurukuta?
1, kunoza imiterere hamwe nubukanishi bwaurukuta. IsubirwamoIfu ya polymer RDP / VAEguhura namazi birashobora gukwirakwira vuba muri emulsiya, kandi bifite imitungo imwe na emulsiyo yambere, ni ukuvuga ko guhumeka kwamazi bishobora gukora firime, iyi firime ifite imiterere ihindagurika cyane, irwanya ikirere cyinshi kandi ifatanye cyane nubutaka butandukanye.
2, kunoza ubumwe bwaurukuta, kurwanya alkali nziza cyane, kwambara birwanya, kongera imbaraga za flexural.
3, kunoza kurwanya amazi no gutembera kwaurukuta.
4, kunoza uburyo bwo gufata amaziurukuta, ongera igihe cyo gufungura.
5, kunoza ingaruka zo guhangana no kongera igihe cyaurukuta.
In urukutairashoboraIfu ya polymer isubirwamoni ingirakamaro cyane, muri rusange, urukuta rwimbere rushobora kongerwamo cyangwa kutaribyo. Ariko mu rukuta rw'inyumaurukutabigomba kongerwaho mugutatanya kwaifu ya polymer, Irashobora kuba mu gutatanya kwaifu ya polymerKuriurukutaifite ubukana bwiza nimbaraga zitinze, kugirango wirinde ko habaho ifu yatinze nibindi bibazo.
Abakiriya bakunze kubaza ibibazo bijyanyeurukuta, nkaurukutabyoroshye gukuramo ifu, ifu ikomeye, cyangwa imbaraga ni nto nibindi. Bose barabiziurukutabakeneye kongeramo selile ether, abakoresha benshi ntibongera redispersibleifu ya polymer. Kuberako bizongera ikiguzi cyaurukuta, kugirango rero uzigame ikiguzi, abakiriya benshi ntibongeraho, niyo mpamvu putty yoroshye gushira ifu ikibazo cyingenzi cyiza!
Celluloseetherirashobora gukuramo ubuhehere iyo bwaguwe namazi. Uruhare nyamukuru rwa selile ni ukugumana amazi, ariko bizagenda buhoroRDPifu nyuma yigihe kinini. Ubu bwoko bwa putty burarekuye, igipimo cyo kwinjiza amazi ni kinini, ifu yoroshye, nta mbaraga, nta elastique. Kunoza ibibazo byavuzwe haruguru birashobora guhindura formulaire, inyongera ikwiye ya bamwe yatatanyeifu ya polymerGutezimbere imbaraga zitinze zaurukuta.
Shyira mubikorwa byo kubyara niba ushobora kongeramo bihagijeRegutatanyaible ifu ya polymer, cyangwa ukoreshe urwego rwo hasi putty idasanzweifu ya polymer, IngarukaUrukutaufite?
urukutairashobora kubaIsubirwamo rya polymer ifu RDP / VAEkongeramo bike, imikorere itaziguye ni putty layer irekuye, ifu yo hejuru, kuringaniza nabi, biragoye gukora firime yuzuye. Uru rukuta rukunda gukonjeshwa, kubyimba, gukuramo, guturika n'ibindi bintu. Niba uri hasiurukutabyatoranijwe, urukuta ruzatanga imyuka yangiza, nka formaldehyde nibindi byangiza umubiri wumuntu biragaragara.
Kubwibyo, icyerekezo cyiza cyo hejuruurukutaumusaruro nuguhitamo hydroxypropyl methyl selileHPMCna redispersibleifu ya polymer RDPnibindi bicuruzwa byongera ibicuruzwa bibisi.
