Whakaahuatanga Hua

Ko tā mātou RN, he mea hanga hei rongoā/hei whakakapi mō te piripiri i ahu mai i te polyurethane hydroxyl, ngā rapa taiao me ngā rapa hangai. Ko te RN he isocyanate kakara NCO, kāore he tae, he iti te matotoru. Nā te pai o te ārai-kōwhai o te RN, he tino pai mō te tono piripiri polyurethane tae mārama. Nā te mea ko te ethyl acetate te whakarewa, ka taea te whakamahi i te RN i ngā whenua e herea ana te whakamahinga o te methylene chloride.

Ngā Āhuatanga o te Hua

Ka ārai i te kōwhai te kiriata o te piri me te kiriata paninga i konatunatua ki te RN i muri i te whakaaturanga ki te mārama UV me/ranei te wera. He pai te kaha o te here o te RN i roto i te PVC me te plasticizer teitei ake, te SBR me te ihirangi hinu teitei ake, te paparanga o runga o te hiako, te hiraka me ētahi atu. Ka taea te whakakotahi i te RN me te polyester polyol me ētahi atu wāhanga kei roto he hydroxyl hei hanga i te wanihi polyurethane wāhanga-rua, i te peita tae rānei. He āhuatanga ōna o te maroke tere me te ārai i te kōwhai. Ko ōna āhuatanga whakamaroke me te kirikiri wawe ko ōna painga nui mō ngā taonga rakau.

Ngā mōhiohio whakamahinga

He piripiri wāhanga-rua te RN. Whai muri i te tāpiri i tētahi ōwehenga o te RN ki te piripiri, me pania te piripiri wāhanga-rua kua rite ki te whakamahi i roto i tētahi wā (te roa o te wā) e whakatauhia ana e te nui o te rapa i roto i te ranunga, engari e ngā kai kē atu o te ranunga (hei tauira, ngā kapia, ngā ārai mate, ngā whakarewa, me ētahi atu). Ki te kore te piripiri e whakamahia i roto i tēnei wā, ka uaua ake te pania, ā, ka tere te piki o tōna matotoru tae noa ki te wā e kore e taea te huri. Nō reira, kāore e whakamahia.

Te Inenga e taunaki ana:

Mō te whakamaroke i te piripiri o te 100 wāhanga taumaha (pbw) i runga i:

Rapa whakapiri-Chloroprene(tata ki te 16% te nui o te rapa)	3-5% pbw RN
Rapa chloroprene(tata ki te 20% te nui o te rapa)	5-7% pbw RN
Polyurethane hauwaiora(tata ki te 15% te nui o te polyurethane)	3-5% pbw RN

Te Tākai me te Rokiroki

Te tākai:

Momo 1. 800g/pounamu, 20 ngā pounamu i roto i te kātene kotahi, 24, 30 rānei ngā kātene i roto i te papa kotahi;

Momo 2. 20kg/pahu, 18 pahu, 27 pahu rānei i roto i te papa kotahi;

Momo 3. 55kg/pahu, 8, 12 rānei ngā pahu i roto i te papa kotahi;

Momo 4. 180kg/pahu, 4 ngā pahu i roto i te papa kotahi

Rokiroki:

Me rongoa ki roto i te ipu hiri taketake 5℃-32℃, ka taea te pupuri i ngā hua mō te 12 marama.

He tino pāngia ā mātou hua katoa e te makuku; ka puta te hauhā waro me te urea kore-rewa i te tauhohenga ki te wai. Mēnā ka pāngia e te hau, e te mārama rānei, ka tere ake te hurihanga o te tae o ngā hua.

(Engari kāore e pāngia te mahi ā-ringa.)

Haumaru:

He āhua kino, he mura rawa, he whakaoho i ngā kanohi, ki te hongia ka pāngia e te mate pāwera. Mā te pā pinepine ka maroke te kiri, ka haurangi rānei. Mā te mamaoa o ngā hua ka ngenge te tangata, ka pōuri hoki.
