ʻIke Laho II: Laho Kūlohelohe（NR)

He polymer kūlohelohe ka laholio kūlohelohe i unuhi ʻia mai ka latex o ka lāʻau Hevea brasiliensis. Hana ʻia ia i mea paʻa elastic ma o nā kaʻina hana e like me ke coagulation a me ka hoʻomaloʻo ʻana. ʻO kāna ʻāpana nui ʻo cis-1,4-polyisoprene (e helu ana no 91% a 94%), a ʻo ke koena he mau mea ʻaʻole laholio e like me nā protein a me nā waikawa momona.

Nā ʻano koʻikoʻi:

1. Nā Waiwai Kino:

(1) Elasticity kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu: Kiʻekiʻe ka ikaika tensile (16.7 - 34.3 MPa), hiki i ka helu elongation ke hiki i ka 650% - 900%, a maikaʻi loa ka elasticity hoʻōla (70% - 95%)

(2) Hoʻololi i ka mahana: Pae mahana hana lōʻihi: -55℃ a i +70℃Ke ahonui pōkole: a hiki i ka 100℃Wahi palupalu haʻahaʻa: ma kahi o -50℃.

(3) Palena uila: Hana pale maikaʻi loa, kūpono no nā uea a me nā kaula

2. Nā nāwaliwali o ke kemika:

(1) Pale ʻaila maikaʻi ʻole: Pehu maʻalahi i ka ʻaila mineral a me ka gasoline (ka nui o ka pehu ʻana: 80% - 300%)

(2) Palekana maikaʻi ʻole i ka ʻelemakule: Hoʻopilikia maʻalahi ʻia e ka ozone, nā kukuna ultraviolet a me nā mahana kiʻekiʻe, a koi ʻia ka hoʻohui ʻana i nā mea anti-kahiko.

(3) Palekana palena ʻia i nā waikawa a me nā alkalis: Hiki ke ʻae ʻia nā waikawa nāwaliwali, akā ʻo nā waikawa ikaika (e like me ka waikawa hydrochloric a me ka waikawa nitric) he mea ʻino loa ia.

3. Nā noi nui:

(1) Nā huila (ʻoi aku ma mua o 70%), nā hose laholio, nā kāʻei conveyor, nā mea hoʻokuʻu haʻalulu, a me nā ʻāpana ukana hoʻoneʻe ʻē aʻe

(2) Nā kāmaʻa laholio, nā mikina lima lapaʻau (e pono ana ka hoʻololi ʻana e hoʻoikaika i ke kūpaʻa ʻana i ka wā)

4. ʻAno huahana: O-ring, huahana i hana ʻia no nā mea kūʻai aku, Rubber Gaskets / Flat Washer Seals / Rubber Spacer / Apo Lahopa Holoi a pēlā aku.
