He rauemi rongonui te putty me te paraikete e whakamahia whānuitia ana i roto i te umanga hanga. He mea nui ēnei mō te whakarite i ngā pakitara me ngā tuanui mō te peita, te hipoki i ngā kapiti, te whakatika i ngā mata pakaru, me te hanga i ngā mata maeneene, ōrite. He maha ngā momo kai e hangaia ana i roto, tae atu ki te sima, te onepu, te raima me ētahi atu tāpiri hei whakarato i te mahi me ngā āhuatanga e hiahiatia ana. Ko te Methylhydroxyethylcellulose (MHEC) tētahi o ngā tāpiri matua e whakamahia ana i roto i te hanga putty me te paura paraikete. E whakamahia ana hei whakapai ake i ngā āhuatanga o ngā paura, hei whakarei ake i ō rātou āhuatanga mahi, hei arotau hoki i ā rātou tono.
Ngā painga o te whakamahi i te MHEC hei hanga putty me te paura gypsum
I ahu mai te MHEC i te cellulose, ā, i hangaia mā te tukanga whakarerekētanga matū. He matū wairewa-wai tēnei e whakamahia whānuitia ana hei whakamātotoru, hei whakaū, hei whakakōpiripiri hoki i roto i te umanga hanga. Ina tāpirihia ki ngā paura putty me te gypsum, ka pania e te MHEC ngā matūriki, ka whakarato i tētahi paparanga tiaki e ārai ana i a rātou kei piri, kei tau. Mā tēnei ka puta he ranunga ōrite, he ngāwari ki te mahi me te whakarato i tētahi whakaotinga pai ake.
Ko tētahi o ngā painga matua o te whakamahi i te MHEC i roto i ngā putty me ngā pāreti ko te whakarei ake i ō rātou āhuatanga pupuri wai. Ka mimiti, ka pupuri hoki te MHEC i te makuku, kia mau tonu ai te whakamahinga o te ranunga, ā, kia kore ai e maroke wawe. He mea nui tēnei i roto i ngā taiao wera, maroke hoki, ina kore e taea te whakamahi wawe i te ranunga, ā, ka ngoikore te āhua o te whakaotinga.
Ka whakapai ake hoki te MHEC i te mahi me te roa o te mahi o ngā pūtu me ngā pāreti. Mā te MHEC ka māmā ake te whakaranu me te paninga o te ranunga mā te pupuri i te makuku me te ārai i te maroke o te ranunga. Hei tāpiri, mā te maeneene, te pata o te MHEC ka taea te horapa ōrite o te pūtu me te stucco ki runga i te mata me te kore e waiho he puranga, he pūriki rānei, kia pai ai te āhua, kia ātaahua ai te whakaotinga.
Haunga te whakarei ake i te kakano me te ngāwari o te mahi o ngā pāreti me ngā pāreti, ka taea hoki e te MHEC te whakapai ake i ō rātou āhuatanga piri. Mā te hanga i tētahi paparanga tiaki huri noa i ngā matūriki, ka whakarite te MHEC kia pai ake te piri ki te mata e rongoatia ana. Ko te hua o tēnei he mata kaha ake, he mata pakari ake, ā, he iti ake te tūponotanga kia pakaru, kia marere, kia tihore rānei i roto i te wā.
Ko tētahi atu painga nui o te whakamahi i te MHEC ki te putty me te paraikete ko te whakanui ake i tō rātou ātete ki te hau me te makuku. Ko te tikanga o tēnei, ina pania te putty, te stucco rānei, ka ātete ki ngā kino o te hau me te makuku, kia mau tonu ai te ataahua me te pakari o te mata mō te wā roa.
Te Arotau i te Mahi o te Putty me te Gypsum mā te whakamahi i te MHEC
Hei whakapai ake i te mahi a te putty me te paura pāreti, he mea nui kia tika te ōwehenga o te MHEC. Ko te tikanga o tēnei, mā te whakamahi i te nui tika o te MHEC ka taea te whakatutuki i te mahi me ngā āhuatanga e hiahiatia ana o te putty, te stucco rānei e hangaia ana.
Me whai whakaaro ki ngā āhuatanga taiao ka pā ki te mahi a te putty me te paura gypsum. Hei tauira, i ngā taiao wera me te maroke, me tāpiri atu pea he MHEC kia mau tonu ai te ora me te ōrite o te ranunga.
He mea nui kia tika te whakamahinga o te putty, te stucco rānei, kia pai ai te mahi. Ko te tikanga o tēnei me whai i ngā tohutohu a te kaihanga me te whakarite kia pai te whakaranu o te ranunga i mua i te whakamahinga. Hei tāpiri, me whakamahi pea i ngā taputapu motuhake hei whakarite kia ōrite te paninga o te putty, te stucco rānei ki te mata e rongoatia ana.
He tāpiringa nui te MHEC e whakamahia ana i roto i te hanga paura putty me te pāreti. Ka whakarei ake i ngā āhuatanga me ngā āhuatanga o ēnei rauemi, ka whakapai ake i tō rātou ngāwari ki te tukatuka, te pupuri wai, te piri me te ātete ki te hau me te makuku. Ka hua ake he āhua pumau, he pakari, he ātaahua hoki te āhua, ā, he iti ake te tūponotanga kia pakaru, kia pakaru, kia tihore rānei i roto i te wā. Hei whakapai ake i te mahi a te putty me te paura gypsum, he mea nui kia tika te horopeta o te MHEC e whakamahia ana, me te whakaaro ki ngā āhuatanga taiao ka pā ki tā rātou mahi. Hei tāpiri, he mea nui kia tika te whakamahi i te putty, i te stucco rānei kia pai ake ai tana mahi me te whakatutuki i ngā hua e hiahiatia ana.
E whakamahia ana te HEMC i roto i ngā hanganga sima hei whakapai ake i ōna āhuatanga. Ko te Hydroxyethyl methylcellulose (HEMC) he matū e whakamahia whānuitia ana i roto i te umanga hanga. Koinei te hononga i waenga i te ngāwari o te mahi, te pupuri wai, te thixotropy, me ētahi atu. I ēnei rā, kei te piki haere te aro ki tētahi momo hou o te cellulose ether. Ko te mea kua nui ake te aro ki tēnei ko te hydroxyethyl methylcellulose (MHEC).
Ko tētahi o ngā mea tino nui e whakatau ana i te kounga o ngā hua sima ko te ngāwari o te mahi a te ranunga. Koinei te ngāwari o te whakaranu, te hanga me te whakanoho i te sima. Hei whakatutuki i tēnei, me wai te ranunga sima kia ngāwari ai te ringi me te rere, engari me matotoru hoki kia mau ai tōna āhua. Ka taea e te MHEC te whakatutuki i tēnei āhuatanga mā te whakanui ake i te matotoru o te sima, ā, ka pai ake ai tōna ngāwari ki te mahi.
Ka taea hoki e te MHEC te whakatere i te makuku o te sima, me te whakapai ake i tōna kaha. Ko te kaha whakamutunga o te sima e whakawhirinaki ana ki te nui o te wai e whakamahia ana hei whakaranu. Mā te nui rawa o te wai ka whakaiti i te kaha o te sima, engari mā te iti rawa o te wai ka uaua rawa te whakamahi. Ka āwhina te MHEC ki te pupuri i tētahi nui o te wai, kia pai ai te makuku o te sima, ā, ka whakatairanga i te hanganga o ngā hononga kaha i waenga i ngā matūriki sima.
Ka āwhina te MHEC ki te whakaiti i te maha o ngā pakaru o te sima. I te wā e mārō ana te sima, ka mimiti te ranunga, ā, ka puta pea ngā pakaru mena kāore e taea te whakahaere i te mimiti. Ka ārai te MHEC i tēnei mimiti mā te pupuri i te nui o te wai i roto i te ranunga, ā, ka ārai i te pakaru o te sima.
He kiriuhi tiaki anō hoki te MHEC i runga i te mata o te sima, e ārai ana i te mimiti o te wai mai i te mata. Ka āwhina anō hoki tēnei kiriuhi ki te pupuri i te makuku taketake o te sima, ā, ka whakaiti anō i te tūponotanga o te pakaru.
He pai hoki te MHEC mō te taiao. Tuatahi, ka pirau, arā, kāore e roa te noho ki te taiao. Tuarua, ka taea e ia te whakaiti i te nui o te sima e hiahiatia ana i roto i ngā kaupapa hanga. Nā te mea ka whakanui ake te MHEC i te kaha mahi me te matotoru o te sima, ka whakaiti i te hiahia mō te wai tāpiri e whakakōkī noa ana i te ranunga sima.
He maha ngā painga o te whakamahinga o te MHEC i roto i te sima, ā, ka taea te whai wāhi nui ki te umanga hanga. Ka whakarei ake i te ngāwari o te mahi o te ranunga sima, ka whakaiti i te maha o ngā kapiti i te wā e whakamaroke ana, ka whakatairanga i te makuku me te kaha o te sima, ā, ka mahi hei kiriata tiaki i runga i te mata o te sima. Hei tāpiri, he pai te MHEC mō te taiao. Nō reira, he hua nui te MHEC mō te umanga hanga nā te mea ka whakapai ake i te kounga o te sima, ā, ka whai hua ki ngā kaimahi me te taiao.
