Te Waikawa Waikawa Metilururo (HPMC)He etera cellulose kore-ionic e whakamahia whānuitia ana i roto i ngā rauemi hanga, inā koa i roto i ngā whakakī hononga (Joint Filler, Tile Grout rānei). Hei tētahi o ngā tāpiringa matua, he mahi nui tā te HPMC. Ko ōna painga matua ko te pupuri wai pai, te matotoru, te whakahinuhinu me te whakapai ake i te mahi hanga.
1. He Tirohanga Whānui mō ngā Whakakī Hononga
Ko te nuinga o ngā whakakī hononga e whakamahia ana hei whakakī i ngā āputa i waenga i ngā taera me ngā kōhatu. Ehara i te mea he whakapaipai noa iho, engari he ātete wai, he ātete harore, he ātete pakaru hoki. Ko ngā whakakī hononga noa ko ngā momo sima, e hangai ana ki te kapia epoxy me ngā momo polymer kua whakarerekētia. He whānuitia te whakamahinga o ngā whakakī hononga sima nā te iti o te utu me te whānui o te whakamahinga.
Heoi, he raruraru anō ō ngā whakakī hononga sima tuku iho pērā i te ngāwari o te pakaru, te kore e piri pai, me te ngoikore o te āhua o te hanganga. Hei whakapai ake i ēnei hapa, ka tāpirihia ngā tāpiringa cellulose ether pērā i te HPMC ki te tauira.
2. Te tūranga o te HPMC i roto i ngā whakakī hononga
2.1. Te pupuri wai nui ake
He tino kaha ngā āhuatanga pupuri wai o te HPMC, ka taea te pupuri i te makuku, te ārai i te tere o te ngaronga wai o te sima, me te whakapai ake i te taumata makuku o te sima, ā, ka whakarei ake i te kaha piri me te ātete ki te pakaru o ngā whakakī hononga. He mea nui rawa atu tēnei mō ngā hanganga paparanga angiangi me ngā taiao maroke.
2.2. Te whakapai ake i te mahi hanga
I te wā o te hanga, ka taea e te HPMC te whakapai ake i te hinu whakahinuhinu me te rere o te hua, kia māmā ake ai te hora me te whakakī i te paru, kia iti ake ai te uaua o te hanga. I taua wā anō, ka taea hoki e ia te ārai i te maroke wawe o te paru, kia roa ake ai te wā mahi me te wā whakatikatika.
2.3. Te whakamātotoru me te whakahaere i te thixotropy
Ka hangaia e te HPMC he otinga korori ōrite, ka pai te matotoru o te paru me te thixotropy, ka ngāwari te whakahaere i te whakakī hononga, ka pai hoki te iri poutū, ka karo i ngā raruraru pēnei i te totohu me te paheke i te wā hanga.
2.4. Te piri pai ake
Mā te nui tika o te HPMC ka pai ake te piri i waenga i te paru me te taha o te taera me te papa, ka whakapai ake i te pumau o te hanganga whānui me te whakaiti i te ngatata me te hinganga i muri mai.
2.5. Ārai-pakaru me te ārai-mimiti
Ka taea e te HPMC te whakaiti i te tere mimiti mā te pupuri i te wai me te whakapai ake i te kiato hanganga, me te whakaiti i te mōrearea o ngā kapiti i puta mai i te ngaronga o te wai me te mimiti i muri i te whakapiripiri. He tino pai mō te whakamahi i ngā wāhi e rerekē haere ana te pāmahana me te haumākū.
2.6. Te ātete huka me te roa o te mau
I ngā taiao pāmahana iti, ka taea e te HPMC te āwhina i te kaihoko whakapiri kia mau tonu tōna ngāwari me te ārai i te kino o te huka; ka taea hoki e tōna hanganga ngota pumau te whakapai ake i te pumau mō te wā roa o te kaihoko whakapiri.
3. Ngā taunakitanga whakamahinga
3.1. Te nui tāpiri kua tūtohutia
Ko te nui o te HPMC e taunakitia ana i roto i te whakakī hononga ko te 0.2%~0.5%, ka taea te whakarerekē kia rite ki te tauira hua. Mēnā he nui rawa te nui o te tāpiri ka heke pea te tere me te kaha o te maroke, nō reira me whakapai ake te tauira me ngā whakamātautau.
3.2. Tikanga marara me te whakarewatanga
Me whakamararatia te HPMC ki roto i te rauemi maroke i te wā e whakamahia ana kia kore ai e haaputuputuhia e te tāpiri tika ki te wai; me tāpiri ki te wai i raro i ngā tikanga whakaoho tere-tiketike hei whakatairanga i te whakarewatanga ōrite.
3.3. Pānga mahi tahi me ētahi atu tāpiringa
Ka taea te whakamahi i te HPMC me te māngaro etera, te paura rapa ka taea te whakamarara anō, te whakaiti wai, me ētahi atu, kia pai ake ai te mahi whānui. Ina koa, ina whakamahia tahitia me te RDP (paura rapa), ka taea te whakapai ake i te ngāwari me te kaha o te here.
4. Ngā taunakitanga kōwhiringa HPMC
He maha ngā momo HPMC, ā, ka pāngia tōna mahi e te nui o te whakakapinga (DS), te matotoru, te rahi o te matūriki me te marara. I roto i ngā whakakī hononga, e taunakihia ana kia tīpakohia ēnei momo HPMC e whai ake nei:
Te matotoru waenga me te matotoru iti (40,000~100,000 mPa·s): me te whai whakaaro ki te hanganga me te pupuri wai, he pai mō te nuinga o ngā hanganga.
Momo inamata (momo maimoatanga mata): he pai mō te tere horapa me te whakaiti i te wā whakarewa.
Hua whakakapinga teitei: he kaha ake te pupuri wai, he pai mō te hanga i ngā wāhi pāmahana teitei, maroke rānei.
Hei tāpiri mahi tino nui i roto ingā whakakī hononga HPMCEhara i te mea ka whakapai ake i te mahi hanga me te roa o te ora o te rauemi anake, engari ka whakapai ake hoki i te kounga whānui me te wheako kaiwhakamahi o te hua. Mā te whanaketanga o ngā rauemi hanga matomato me te taiao, ka nui ake te mahi a te HPMC i roto i ngā whakakī hononga me ētahi atu matū hanga nā ōna painga pēnei i te hanga koiora, te kore-paitini me te pirau.
