He aha ka ʻokoʻa ma waena o ka bakelite injection molding machine a me ka plastic injection molding machine?

He aha ka ʻokoʻa ma waena o ka bakelite injection molding machine a me ka plastic injection molding machine?

I kēia manawa, hoʻohana nui nā mea hana hana hoʻoheheʻe injectionbakelite injectionnā mīkini hoʻoheheʻe aiʻa ʻiʻonā mīkini hoʻoheheʻe.Aia nā ʻokoʻa like ʻole ma waena o Dewei casting bakelite injection molding machines a me ka plastic injection molding machines.ʻO ka Bakelite ka PF (phenolic resin).ʻO ka Bakelite kahi ʻano plastik i hana mua ʻia, nāna i hoʻokō i ka hana ʻenehana ma ʻAmelika i ka makahiki 1910. E ʻike kākou i ka ʻokoʻa?
ʻO nā mea maka no ka hana ʻana i ka bakelite ka nui o nā phenols a me nā aldehydes, a hoʻohana mau ʻia ka phenol a me formaldehyde.Loaʻa iā lākou ma ka polycondensation ma lalo o ka catalysis o ka waikawa, alkali a me nā catalysts ʻē aʻe.ʻO ka hana ʻenehana ka nui o ka hana maloʻo a me ka hana pulu.

Hiki i ka Phenol a me ka aldehyde ke hana i ʻelua ʻano PF ma lalo o ka hana a nā mea hoʻoheheʻe like ʻole: ʻo ka PF thermoplastic a ʻo ka PF thermosetting kekahi.Hiki ke ho'ōla 'ia ka mea mua i loko o ke kino ma ka ho'ohui 'ana i ka lā'au lapa'au a me ka ho'omehana 'ana, a'o ka hope hiki ke lilo i kino kino e like me ka lō'ihi o ka ho'omehana 'ana me ka lā'au lapa'au.
ʻO ka thermoplastic pf a i ʻole thermosetting PF, hiki ke hoʻohana ʻia ka pūnaewele hoʻololi i hana ʻia e ka curing.ʻO ke kaʻina hana ho'ōla ka hoʻomau ʻana o ka hopena polycondensation nui a me ka hoʻokumu ʻana o ka huahana nui loa.He ʻokoʻa kēia kaʻina hana mai ka hoʻoheheʻe ʻana a me ka hoʻōla ʻana o ka thermoplastic maʻamau.ʻAʻole hiki ke hoʻohuli ʻia, me nā kaʻina hana kino a me nā hana kemika.
Hiki ke hoʻoheheʻe ʻia ka PF e ke ʻano like me ka thermoplastic.ʻO ka Pf i hoʻohana ʻia no ka hoʻoheheʻe ʻana e pono ai ka wai maikaʻi, ka hoʻoheheʻe ʻana ma lalo o ke kaomi haʻahaʻa haʻahaʻa, ka rigidity thermal kiʻekiʻe a me ka wikiwiki paʻakikī, ka nani o ka ʻili o nā ʻāpana plastik, ka hoʻoheheʻe ʻana a ʻaʻohe pollution i ka mold.Eia nō naʻe, loaʻa nā hemahema i ka hoʻopili ʻana i ka injection.No ka laʻana, ua kaupalena ʻia ka hoʻoheheʻe ʻia e ke ʻano o ka hoʻopihapiha, ʻaʻole kūpono ia no ka hoʻoheheʻe ʻana i nā ʻāpana plastik me nā mea hoʻokomo hou aku, a ʻo ka nui o nā puka a me nā kahawai kahe ma hope o ka hoʻōla ʻana ʻaʻole hiki ke hana hou ʻia a hiki ke hoʻolei wale ʻia.
I ka pōkole, hiki ke hana ʻia ka thermoplastic PF e ka mīkini hoʻoheheʻe injection maʻamau, akā pono e mālama pono ʻia nā kūlana kaʻina.Pono e hana ʻia ka Thermosetting pf e ka PF mīkini hoʻoheheʻe kūikawā kūikawā (he ʻokoʻa ka pahu a me ka screw me ka mīkini hoʻoheheʻe maʻamau), a pono hoʻi e hoʻohana ka mold i kahi hoʻolālā hoʻolālā kūikawā!
ʻO Sino Vision Vehicle & Service Co., Limited, aia ma Huangyan Town, Taizhou, e kālele ana i ka hana hoʻoheheʻe ʻana e like me ka bakelite, BMC injection molding a me ka precision plastic injection molding.Hoʻohana nui ʻia nā huahana bakelite a me BMC injection molding i nā ʻano mea kīhini āpau, electromechanical a me nā mea pono hale.Loaʻa i ka hui kahi ʻenekinia ikaika a me ka hui ʻenehana, ka mea i kūpaʻa i ka hana ʻana i nā huahana me ke ʻano kiʻekiʻe a me ke kumukūʻai nani no nā mea kūʻai aku, hiki ke hoʻokō i nā pono hana like ʻole o nā mea kūʻai.
