Kana uchigadzira uye kushandisa putty poda, isu tinosangana nematambudziko akasiyana siyana. Nhasi, zvatiri kutaura nezvazvo kuti kana iyo puroyi yakasanganiswa nemvura, paunonyanya kumutsa, mutambi wekutonga achava, uye chidimbu chekuparadzaniswa kwemvura zvichave zvakakomba.
Iyo inokonzeresa dambudziko iri nderekuti hydroxyprupyl methylcellose yakawedzerwa muPutty poda haina kukodzera. Ngatitarisei tarisiro yekushanda uye kuti tingazvigadzirisa sei.
Iyo nheyo yeiyo putty poda ichitora mutete uye akaonda:
1. Iyo viscosity ye hydroxyprupyl methylcellose haina kusarudzwa zvisiri izvo, iyo viscosity yakaderera, uye kumiswa kwekumiswa hakuna kukwana. Panguva ino, kuparadzaniswa kwemvura kwakasimba kuchaitika, uye kumiswa kweunifomu hakuzoratidzwa;
2. Wedzera yemvura-kuchengetedza mumiririri kuti utore poda, iyo ine yakanaka mvura-yekuchengetedza maitiro. Kana iyo putty ichinyungudika nemvura, inokiya yakawanda yemvura. Panguva ino, mvura zhinji inoyerera mumasumbu emvura. Nekukurudzira mvura yakawanda yakaparadzaniswa, saka dambudziko rakajairika nderekuti rakawanda raunomutsa, iye akaonda anozova. Vanhu vazhinji vakasangana nedambudziko iri, iwe unogona kuderedza nemazvo huwandu hwekwereta cellulose kana kuderedza iyo yakawedzera mvura;
3. Iyo ine humwe hukama nehurongwa hwe hydroxyprupylpropropyl methylcellose uye ine thisiotropy. Naizvozvo, mushure mekuwedzera cellulose, iyo yese coating ine imwe thixotropy. Kana iyo putty yakakurudzirwa nekukurumidza, chimiro chayo chose chinopararira uye chave chakaonda uye chakaonda, asi kana chasara, chichava zvishoma nezvishoma.
Solution: Kana uchishandisa putty poda, kazhinji wedzera mvura uye kukurudzira mvura uye kukurudzira kuti isvike padanho rakakodzera, asi kana uchiwedzera mvura, uchaona kuti mvura yakawanda inowedzerwa, iyo yakaonda inova. Chii chiri chikonzero cheizvi?
1. Cellulose inoshandiswa seyakavharira uye nemvura-yekuchengetedza mumiririri muhomwe, asi nekuda kweiyo cellootropy pachezvako, kuwedzera cellulose muPutty Poda inotungamira kune iyo THOLOTROPY mushure mekuwedzera mvura kune iyo putty;
2. Iyi thiskotropy inokonzerwa nekuparadzwa kwechimiro chakasarudzika chezvikamu mune iyo putty poda. Ichi chimiro chinogadzirwa kuzorora uye kugumburwa pasi pekushushikana, ndiko kuti, viscosity inoderera pasi pekusimudzira, uye visikoka pakuzorora, saka kuchave nenhengo yekuti iyo phenomenon iyo denty iyo yakaonda sezvinowedzerwa nemvura;
3. Pamusoro pezvo, kana iyo purodhi iyo iri kushandiswa, iyo inofamba nekukurumidza nekuti iyo yekuwedzera kweiyo ash calcium poda ine chekuita nekuoma kwemadziro. Iyo prolling uye kutenderera kweiyo putty poda inoenderana neyekuchengeterwa mvura yekuchengetedza mvura;
4. Naizvozvo, kuitira kudzivirira zvisina basa, isu tinofanira kuteerera matambudziko aya patinoishandisa.
