ʻOi aku ka maikaʻi o ka hoʻoheheʻe ʻana o ka PU a i ʻole ka ʻōpala ʻōpala no ka pā hale mālama ʻoihana?

Ke koho ʻana i nā mea o nā mea hoʻolale hoʻopaʻa ʻana, ʻo PU (polyurethane) a me ka rubber i kēlā me kēia i ko lākou pono ponoʻī a me nā hemahema, pono e hoʻoholo ʻia e like me ke ʻano hoʻohana a me nā koi.

1. Nā hiʻohiʻona o nā mea hoʻolele PU
1) Pono:
A. ʻO ke kūpaʻa ʻaʻahu ikaika: He kiʻekiʻe ka paʻakikī o ka mea PU a kūpono no ka hoʻohana pinepine ʻana a i ʻole nā hiʻohiʻona koʻikoʻi (e like me nā hale kūʻai a me nā papa hana). ʻOi aku ka lōʻihi o kona ola ma mua o ka lāʻau.
B. ʻO ka hiki ke halihali i ka ukana maikaʻi: kūpono no ka lawe ʻana i nā pahu waiho kaumaha (e like me nā papa hana ʻoihana).
C. Kū'ē Kemika/Aila: ʻAʻole hiki ke ʻino ʻia e ka ʻaila a i ʻole nā solvents, kūpono no nā kaiapuni e like me nā laboratories a me nā hale hana.
D. ʻOi aku ka maikaʻi o ka hoʻohaʻahaʻa ʻana i ka walaʻau: ʻOiai ʻaʻole e like me ka ʻōpala, ʻoi aku ka mālie ma mua o nā mea paʻakikī e like me ka nylon.
2) Nā hemahema:
ʻAʻole lawa ka elasticity maikaʻi ʻole: ʻAʻole lawa paha ka hopena o ka haʻalulu ma nā ʻili ʻili e like me nā papahele sima.
B. ʻO ka paʻakikī haʻahaʻa haʻahaʻa: E emi ana ka loli ma nā wahi anu.
2. ʻO nā hiʻohiʻona o nā mea hoʻoheheʻe lāʻau
1) Pono:
A. ʻO ka haʻalulu a me ka anti slip: He palupalu ka lāʻau a kūpono hoʻi no nā ʻili laulima e like me nā tile a me nā papahele lāʻau, e hoʻopaʻa pono i nā haʻalulu a pale i ka lepo.
B. Ka hopena ho'ēmi leo maikaʻi: kūpono i nā keʻena, nā hale, a me nā wahi ʻē aʻe e pono ai ka mālie.
C. Hiki ke hoʻololi i ka wela ākea: mālama i ka elasticity ma nā haʻahaʻa haʻahaʻa.
2) Nā hemahema:
A. Nawaliwali i ke komo 'ana: 'O ka ho'ohana lō'ihi 'ana ma luna o ka 'ilikai 'o ia ka mea hiki ke ho'ohana 'ia i ka lole a me ka waimaka.
B. E maʻalahi i ka makahiki: Hiki i ka loaʻa ʻana i ka momona a me ka pāhawewe ultraviolet i ka pohā.
Ma muli o nā pono maoli, ʻoi aku ka maʻamau o ka PU i nā hiʻohiʻona ʻoihana a ʻoi aku ka maikaʻi o ka lāʻau no nā kaiapuni home.
