inoa huahana:phenolic resin
Hōʻano molekala:
No CAS:9003-35-4
Huahana molecular structure:
Hoʻomākaukau ʻia ka resin Phenol-formaldehyde penei:
C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
Hoʻokahi-ʻanuʻu Resins. He kiʻekiʻe ka lakio o ka formaldehyde i ka phenol e hiki ai i ke kaʻina hana thermosetting ke hana me ka hoʻohui ʻole o nā kumu kumu o nā loulou keʻa.
ʻElua mau ʻāpana Resins. He haʻahaʻa ka ratio o ka formaldehyde i ka phenol e pale ai i ka hopena thermosetting mai ka wā e hana ʻia ai ka resin. I kēia manawa ua kapa ʻia ka resin novolac resin. A laila, hoʻokomo ʻia ka hexamethylenetetramine i loko o ka mea e hana ai ma ke ʻano he kumu o nā loulou kemika i ka wā o ka hana ʻana (a me ka hoʻololi ʻana i ka thermoset a i ʻole ke kūlana hoʻōla).
Hoʻohana ʻia nā resins Phenolic no nā ʻāpana kūʻai haʻahaʻa e koi ana i nā waiwai insulating uila maikaʻi, pale ʻana i ka wela, a i ʻole ke kūʻē kemika. ʻO ka maʻamau o ke ola o kēia resin ma kahi o 1 mahina ma 21.1 ° C. Hiki ke hoʻonui ʻia ma ka mālama ʻana i loko o ka friji ma 1.6 a 10 ° C. ʻO ka hoʻololi ʻana i ka catalyst (e like me ka mānoanoa o ka hoʻolei) a me ka hoʻonui ʻana i ka mahana hoʻōla i 93 ° C e hoʻololi i ka manawa hoʻōla mai ka lōʻihi o 8 mau hola a hiki i ka 15 min.
Loaʻa kekahi shrinkage i ka hoʻolei ʻana (0.012 a 0.6 mm / mm), e pili ana i ka nui o ka hoʻopiha, ka nui o ka catalyst, a me ke ʻano o ka hoʻōla. ʻO nā pōʻai hoʻōla ʻoi aku ka wikiwiki o ka emi ʻana. No ka mea hiki ke hoʻolōʻihi ʻia ka pōʻaiapuni lapaʻau, hoʻohana ʻia nā phenolics i nā hana pōkole.
Hoʻopau maʻalahi ʻia nā ʻāpana phenolic mai ka mold inā hoʻohana ʻia nā mea hoʻokaʻawale i ʻōlelo ʻia e ka mea hoʻolako. Hoʻomaikaʻi ʻo Posturing i nā waiwai kumu o ka hoʻolei ʻana.
Hiki iā Chemwin ke hāʻawi i ka nui o nā hydrocarbons nui a me nā mea hoʻoheheʻe kemika no nā mea kūʻai aku ʻoihana.Ma mua o kēlā, e heluhelu i ka ʻike kumu e pili ana i ka hana ʻana me mākou:
1. Palekana
ʻO ka palekana kā mākou mea nui. Ma waho aʻe o ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike e pili ana i ka hoʻohana palekana a me ka hoʻohana ʻana i ka nohona o kā mākou huahana, ua paʻa pū mākou i ka hōʻoia ʻana e hōʻemi ʻia nā pilikia palekana o nā limahana a me nā mea hana ʻaelike i kahi liʻiliʻi kūpono a hiki. No laila, koi mākou i ka mea kūʻai aku e hōʻoia i ka hoʻokō ʻana i nā kūlana palekana kūpono no ka wehe ʻana a me ka mālama ʻana ma mua o kā mākou hoʻouna ʻana (e ʻoluʻolu e nānā i ka appendix HSSE ma nā ʻōlelo a me nā kūlana kūʻai ma lalo). Hiki i kā mākou mau loea HSSE ke hāʻawi i ke alakaʻi i kēia mau kūlana.
2. Keʻano hoʻouna
Hiki i nā mea kūʻai ke kauoha a hāʻawi i nā huahana mai chemwin, a i ʻole hiki iā lākou ke loaʻa nā huahana mai kā mākou hale hana. ʻO nā ʻano kaʻa kaʻa i loaʻa ke kaʻa kaʻa, kaʻaahi a i ʻole ka halihali multimodal (e pili ana nā kūlana kaʻawale).
I ka hihia o nā koi o ka mea kūʻai aku, hiki iā mākou ke kuhikuhi i nā koi o nā moku a i ʻole nā pahu pahu a kau i nā kūlana palekana / loiloi kūikawā a me nā koi.
3. Ka nui kauoha liʻiliʻi
Inā kūʻai ʻoe i nā huahana mai kā mākou pūnaewele, ʻo ka liʻiliʻi liʻiliʻi he 30 tons.
4. Uku
ʻO ke ala uku maʻamau ka unuhi pololei ʻana i loko o 30 mau lā mai ka invoice.
5. Nā palapala hoʻouna
Hāʻawi ʻia kēia mau palapala i kēlā me kēia hoʻouna:
· Bill of Lading, CMR Waybill a i ʻole nā palapala halihali e pili ana
· Palapala hōʻoia o ka nānā ʻana a i ʻole Conformity (inā koi ʻia)
· Nā palapala pili i ka HSSE e like me nā lula
· Nā palapala dute e like me nā lula (inā pono)
