Pehea i hana ʻia ai ka resin phenol formaldehyde?

Pehea i hana ʻia ai ka resin phenol formaldehyde?

ʻO ka Bakelite ka resin phenolic.ʻO Phenolic resin (PF) kahi ʻano o nā huahana plastik ʻoihana.ʻO nā mea maka o ka hana phenolic resin ka nui o ka phenol a me ka aldehyde, a ʻo ka phenol a me ka formaldehyde ka mea maʻamau.Hoʻopili ʻia lākou e ka hopena condensation ma lalo o ka catalysis o ka waikawa, base a me nā catalysts ʻē aʻe.ʻElua ʻano hana ʻoihana: ka hana maloʻo a me ka hana pulu.

Ma lalo o ka hana a nā catalysts like ʻole, hiki i ka phenol a me ka aldehyde ke hana i ʻelua ʻano resins phenolic: ʻo kekahi ka thermoplastic phenolic resin, ʻo ka thermosetting phenolic resin.Hiki ke ho'ōla 'ia ka mea mua i loko o ka hale poloka ma ka ho'ohui 'ana i ka lā'au lapa'au a me ka ho'omehana 'ana, a'o ka hope hiki ke ho'ōla 'ia i loko o ka hale poloka ma ka ho'omehana 'ana me ka ho'ohui 'ole i ka lā'au lapa'au.

Hiki ke hoʻohana wale ʻia ka Thermoplastic phenolic resin a me ka thermosetting phenolic resin ma o ka ʻoihana hoʻololi i hana ʻia e ka curing.ʻO ke kaʻina hana hoʻōla ka hoʻomau ʻana o ka polycondensation shape a me ka hoʻokumu ʻana i nā huahana shape.He ʻokoʻa kēia kaʻina hana mai ka hoʻoheheʻe ʻana a me ka hoʻōla ʻana o nā thermoplastics maʻamau.ʻAʻole hiki ke hoʻohuli ʻia nā kaʻina hana kino a me ke kemika.

Hiki ke hoʻoheheʻe ʻia ka resin Phenolic ma ke ʻano like me ka thermoplastic.PF no ka hoʻoheheʻe ʻanaPono ka wai maikaʻi, hiki ke hoʻoheheʻe ʻia ma lalo o ke kaomi haʻahaʻa haʻahaʻa, ʻo ka ʻoʻoleʻa wela kiʻekiʻe, ka wikiwiki paʻakikī, ka ʻili maikaʻi o nā ʻāpana plastik, maʻalahi ka demoulding, ʻaʻohe pollution mold.Eia nō naʻe, ʻo ka hoʻoheheʻe ʻia ʻana he mau hemahema kekahi.No ka laʻana, ua kaupalena ʻia ka heheʻe e ke ʻano o ka mea hoʻopihapiha, no laila ʻaʻole kūpono ke hoʻohana ʻana i nā mea hoʻokomo hou aku e hana i nā ʻāpana plastik.ʻAʻole hiki ke hana hou ʻia ka nui o nā ʻīpuka a me nā kahawai ma hope o ka mālama ʻana, a hiki ke hoʻolei wale ʻia.

Ma kahi huaʻōlelo, hiki ke hana ʻia ka resin phenolic thermoplastic e ka mīkini hoʻoheheʻe injection maʻamau, akā mālama paʻa ʻia nā kūlana kaʻina.Pono e hana ʻia ka Thermosetting phenolic resin e kahi mīkini hoʻoheheʻe hoʻoheheʻe kūikawā no ka resin phenolic, a hoʻohana pū ka mold i kahi hoʻolālā hoʻolālā kūikawā.

Hoʻohana nui ʻia ia mamea uila, nā kumu, nā ipu kukui,nā pūpū mīkini sandwich, etc;Eia naʻe, ʻo kāna hana palupalu a me ke kaʻina hana paʻakikī hiki ke kaupalena i kona hoʻomohala ʻana.Me ka puka ʻana o nā plastics ʻē aʻe, ʻaʻole maʻalahi nā huahana bakelite i kēia manawa.ʻOiai pono e hoʻomehana ʻia nā huahana bakelite no ka hoʻoheheʻe ʻana, ʻoi aku ka lōʻihi o ka manawa hana ma mua o nā plastics maʻamau, a ʻoi aku ka nui o ka lole ʻeleʻele, kahi e koi ai i nā koi kiʻekiʻe no ke kila, akā no kona kūlana maikaʻi i ke kumukūʻai o nā mea maka, ʻo ia. he pani no na apana plastik he nui.
