Te Whakanui i te Kaha o te Piripiri: Me pēhea te hurihanga o te Paura Polymer Whakamarara Anō (RDP) i ngā Mota Here

He aha te Hiranga o te Kaha Piri i roto i te Hononga Moata

Ko te piri te tūāpapa o te hononga pai o ngā moata. Ahakoa te whakau i ngā taera, te whakatika i te raima, te tāuta rānei i ngā pūnaha whakamahana, me:

• Ātete ki ngā ahotea kutikuti me ngā ahotea kumemai i ngā huringa taiao, i ngā kawenga ā-pūkaha rānei.
• Kia mau tonu te kotahitanga mō te wā roaahakoa te pānga o te makuku, te panonitanga o te pāmahana, te wiri rānei.
• Ārai i te wehewehengai waenganui i ngā papa (hei tauira, te raima, te rakau, te gypsum rānei).

Kāore i te ngāwari, kāore hoki i te piri ngā moata sima tuku iho i raro i ngā āhuatanga hihiri. Koinei te wāhi e whai wāhi ai te RDP hei whakarei ake i te mahi.

Te Whakapai Ake a te RDP i te Piripiri i roto i ngā Moata

Ko te Paura Pūmua Whakamarara Anō he copolymer whakamaroke-rehu (hei tauira, te vinyl acetate-ethylene) ka whakaemulsified anō ina konatunatua ki te wai. I roto i ngā moata honohono, ka mahi te RDP mā te:

1. Te Hanga i tētahi Kiriata PolymerI te wā e mārō ana te moata, ka hangaia e te RDP he whatunga ngāwari, e uru ana ki roto, e herea ana ngā matūriki sima me ngā mea whakahiato. Ka honoa e tēnei kiriata ngā āputa i waenganui i te moata me te papa, ka whakapai ake i te piri ā-ringa.
2. Te Whakaiti i te PakaruHe rerekē tēnei i ngā matihiko sima mārō, ka tāpirihia e te RDP te ngāwari, ka taea ai e ngā moata te mimiti i te ahotea me te kore e pakaru.
3. Te Whakapai Ake i te MākūKa whakarei ake te RDP i te kaha o te moata ki te "pupuri" i ngā mata pūngoi, maeneene rānei, ahakoa i roto i ngā āhuatanga uaua.

Ngā Painga Matua o te RDP i roto i te Hononga Mota

1. Te Kaha Here Teitei Ake: Ka tutuki i ngā moata kua whakarerekētia e te RDP te tae ki2x te piri kaha akeki te whakataurite ki ngā ranunga kāore i whakarerekētia, e ai ki ngā whakamātautau ASTM C1583.
2. Ātete NgatataKa whakaitihia e te kiriata pūmua ngā kapiti moroiti i puta mai i te whakahekenga, te whakawhānui rānei i te wera.
3. Ātete WaiKa whakaitihia e te RDP te mimiti wai, ka tiaki i te hononga mai i te pirau o te makuku.
4. Ngā momo mahiHe pai te mahi ki runga i ngā papa rerekē, tae atu ki te raima, te uku, me ngā papa whakamahana EPS.
5. Te āheinga ki te mahiMā te RDP ka pai ake te horapa o te moata, ka ōrite te tono, ā, ka whakaiti i te wā mahi.

RDP i roto i te Mahi: Ngā Taupānga o te Ao Tūturu

• Ngā Piripiri TāeraMā te RDP ka mau tonu te piri o ngā taera ki ngā wāhi maku (hei tauira, ngā kaukau, ngā puna kaukau) me ngā wāhi e nui ana te haere o te tangata.
• Ngā Pūnaha Whakamarumaru Pakitara o Waho: Ka whakarei ake i te piri o ngā paninga turanga ki ngā panera whakamahana, ka ārai i ngā rahunga o te pūnaha.
• Ngā Mota Whakatika KonukuraitiKa whakaora i ngā hononga hanganga o ngā hanganga tawhito me te kore e motu.
• Ngā Matū Whakatakoto Papa: Ka waihanga i tētahi hononga maeneene i waenga i ngā mata tawhito me ngā mata hou.

Te Mahi Tahi me ngā Etera Cellulose

Mō ngā kaihanga e whakamahi ana i ngā etera cellulose (hei tauira, HPMC, MHEC), ka mahi te RDP hei tāpiringa tāpiri. Ahakoa ka pupuri wai, ka whakamātotoru hoki ngā etera cellulose, ka tāpirihia e te RDP:

• Whakarei ake i te pirimō ngā tono poutū, o runga rānei e hiahiatia ana.
• Ngāwarihei whakahaere i te nekehanga o te papa.
• Te pakarii ngā āhuarangi kino.

Mā te whakakotahi i ngā tāpiringa e rua ka hangaia he moata e tutuki ana i ngā paerewa teitei rawa atu mō ngā piripiri moenga-angiangi, ngā whakakoi, me ngā pūnaha whakatika.
