1.ʻO ka hoʻomaʻemaʻe plastik
ʻO ka wehewehe ʻana o ka plasticization: ʻO ke ʻano o ka hoʻololi ʻana o ka lāʻau mai kahi mea elastic i kahi mea palaki ma lalo o ka mana o nā mea waho i kapa ʻia ʻo plasticization.
(1)Kumu Hoomaemae
a.E ho'ā i ka ʻōpala maka e hoʻokō i kahi pae o ka plasticity, kūpono no nā pae hope o ka hui ʻana a me nā kaʻina hana ʻē aʻe
b.Hoʻohui i ka plasticity o ka ʻōpala maka a hōʻoia i ka maikaʻi o ka mea lāʻau
(2)Pono ka hoʻoholo ʻana o ka pūhui plastik: Mooney ma luna o 60 (theoretical) Mooney ma luna o 90 (maoli)
(3)Mīkini hoʻomaʻemaʻe plastik:
a. Hale wili wehe
Nā hiʻohiʻona: Kiʻekiʻe ka hana ikaika, haʻahaʻa hana pono, maikaʻi ʻole nā kūlana hana, akā maʻalahi ia, me ka haʻahaʻa haʻahaʻa, a kūpono i nā kūlana me nā loli he nui ʻO ka ratio wikiwiki o nā pahu ʻelua o ka wili hāmama: mua a hope (1:1.15). -1.27)
Nā ʻano hana: ʻO ke ʻano hoʻomaʻemaʻe plastic pass thin, ke ʻano hoʻomaʻemaʻe plastic rolling, ke ala piʻi ʻana, ke ʻano plasticizer kemikal.
ʻO ka manawa hana: ʻAʻole pono ka manawa hana ma mua o 20 mau minuke, a ʻo ka manawa kaʻa he 4-8 mau hola
b.Mea hui kuloko
Nā hiʻohiʻona: ʻO ka hana kiʻekiʻe ka maikaʻi, ka hana maʻalahi, ka haʻahaʻa haʻahaʻa o ka hana, a me ke ʻano like ʻole o ka plasticity. Eia nō naʻe, hiki i nā wela kiʻekiʻe ke hoʻemi i nā waiwai kino a me nā mīkini o ka mea lāʻau
Kaʻina hana: Ke kaupaona ana → Hānai → Plasticizing → Hoʻokuʻu → Hoʻohuli → Paʻi → Hoʻoluʻu a wehe ʻana → Waihona
Ka manawa hana: 10-15 minuke Kaʻa kaʻa: 4-6 hola
(4)Pākīpika mau
ʻO nā mea Rubber pono e hoʻoheheʻe pinepine ʻia, ʻo ia ka NR, NBR paʻakikī, ka ʻōpala paʻa, a me nā mea me ka helu Mooney o 90 a i luna.
2.Huihui
ʻO ka wehewehe ʻana o ka hui ʻana, ʻo ia ka hoʻohui ʻana i nā mea hoʻohui like ʻole i ka lāʻau e hana ai i kahi pahu hui
(1)E wehe i ka huila no ka hui ʻana
a.Wrapping roller: E wīwī i ka ʻōpala maka ma ka wili mua a loaʻa kahi kaʻina hana preheating pōkole o 3-5 mau minuke.
b.Kaʻina ʻai: E hoʻohui i nā mea hoʻohui e pono e hoʻohui ʻia i kekahi kauoha. I ka hoʻohui ʻana, e noʻonoʻo i ka nui o ka glue i hōʻiliʻili ʻia. He mea paʻakikī ka hoʻohui ʻana i ka liʻiliʻi, ʻoiai ʻoi aku ka nui a ʻaʻole maʻalahi ka hui ʻana
ʻO ke kaʻina hanaʻai: ʻōpala maka → mea hana, kōkua hana → sulfur → hoʻopiha, mea hoʻoluliluli, dispersant → kōkua hana → accelerator
c.Kaʻina hana hoʻomaʻemaʻe: hiki ke hoʻohui maikaʻi, wikiwiki, a ʻoi aku ka like
ʻAno pahi: a. ʻO ke ʻano pahi ʻoi aku (eight knife method) b. ʻO ke ʻano o ka ʻōwili ʻana i ka huikolu c. Ke ʻano hana wili d. ʻO ke ʻano o ka gluing (ke ʻano pahi hele wāwae)
d.ʻO ke kumu hoʻohālikelike no ka helu ʻana i ka mana hoʻouka o ka wili hāmama ʻo V=0.0065 * D * L, kahi V - leo D ke anawaena o ka huila (cm) a ʻo L ka lōʻihi o ka ʻōwili (cm)
e.Ka wela o ka wili: 50-60 degere
f.Ka manawa hui: ʻAʻohe hoʻoponopono kikoʻī, pili ia i ka mākaukau o ka mea hoʻohana
(2)ʻO ka hui pū ʻana o loko:
a.Hoʻokahi pae hui ʻana: Ma hope o hoʻokahi pae o ka hui ʻana, penei ke ʻano o ka hui ʻana: ʻōpala maka → mea liʻiliʻi → mea hoʻoikaika ikaika → mea hoʻomaʻamaʻa → hoʻokuʻu ʻia ka lāʻau → hoʻohui i ka sulfur a me ka accelerator i ka papa paʻi → unloading → hoʻoluʻu a kaʻa.
b.ʻO ka hui ʻana o ka pae ʻelua: Ka hui ʻana i ʻelua mau pae. ʻO ka pae mua, ʻo ia ka lāʻau lapaʻau → mea liʻiliʻi → mea hoʻoikaika → mea hoʻomaʻamaʻa → hoʻokuʻu ʻia → kaomi papa → hoʻoluʻu. ʻO ka lua o ka hana, ʻo ia ka makuahine → sulfur a me ka accelerator → kaomi papa → hoʻolili
(3)ʻO nā pilikia maʻamau o ka maikaʻi me ka lāʻau huikau
a.Huihui hui
ʻO nā kumu nui: ʻaʻole lawa ka hoʻomaʻemaʻe ʻana i ka ʻōpala maka; ʻO ka nui o ka roller pitch; ʻO ka hiki ke hoʻopili nui; ʻO ka wela nui o ka wili; Aia i loko o ka hui pauda nā ʻāpana koʻikoʻi a i ʻole nā pūʻulu;
b.ʻOi aku ka nui a i ʻole lawa ʻole ka ʻumekaumaha kikoʻī a i ʻole ka puʻunaue like ʻole
Ke kumu: Ke kaupaona pololei ʻole o ka mea hoʻohuihui, ka hui ʻana hewa ʻole, ka waiho ʻana, ka hoʻohui hewa a i ʻole ka waiho ʻana i ka wā o ka hui ʻana.
c.Pāpī hau
ʻO ka mea nui ma muli o ka hoʻohana nui ʻana o kekahi mau mea hoʻohui, i ʻoi aku ka nui o ko lākou solubility i ka lāʻau i ka lumi wela. Ke hoʻopiha nui ʻia ka hoʻopiha keʻokeʻo, e puhi pū ʻia nā mea keʻokeʻo, ʻo ia ka mea i kapa ʻia ʻo ka pauka
d.Kiʻekiʻe loa ka paʻakikī, haʻahaʻa loa, ʻaʻole like
ʻO ke kumu, ʻaʻole pololei ke kaupaona ʻana o nā mea vulcanizing agents, accelerators, softeners, reinforcing agents, a me ka rubber raw, a ke kumu ia i ka hoʻohui hewa ʻole a i ʻole ka hoʻohui ʻana, e hopena i ka hui ʻole ʻana a me ka paʻakikī ʻole.
e.Puhi: ʻO ke ʻano vulcanization mua o nā mea hao
Ke kumu: ka hui pono ʻole o nā mea hoʻohui; ʻO ka hana hui ʻana i ka lāʻau lapaʻau kūpono ʻole; ʻO ka hoʻoluʻu kūpono a me ke kaʻa; Nā hopena o ke aniau, etc
3.Sulfurization
(1)Ka liʻiliʻi o nā mea
a.ʻAʻole hiki ke hoʻokuʻu ʻia ka ea ma waena o ka ʻōpala a me ka lāʻau
b.ʻAʻole lawa ke kaumaha
c.ʻAʻole lawa ke kaomi
d.ʻAʻole maikaʻi ka wai o ka mea hao
e.ʻOi aku ka wela o ka poʻi a me ka mea puhi ahi
f.ʻO ka ʻāna mua ʻana o nā mea lāʻau (mea make)
g.ʻAʻole lawa ka mānoanoa mea a lawa ʻole ke kahe
(2)Nā pōpō a me nā pores
a.ʻAʻole lawa ka vulcanization
b.ʻAʻole lawa ke kaomi
c.ʻO nā mea haumia a i ʻole nā ʻaila ʻaila i loko o ka mea hoʻoheheʻe a i ʻole ka mea hao
d.He kiʻekiʻe loa ka mahana o ka vulcanization mold
e.ʻAʻole liʻiliʻi ka mea vulcanizing i hoʻohui ʻia, lohi loa ka wikiwiki vulcanization
(3)Kaʻili kaumaha a me ka māhā
a.ʻOi aku ka wikiwiki o ka vulcanization, a ʻaʻole lawa ka kahe o ka lāʻau
b.ʻO nā ʻeleʻele lepo a i ʻole nā ʻōpala paʻa
c.Nui loa ka hoʻokaʻawale ʻana a i ʻole ka mea hoʻokuʻu
d.ʻAʻole lawa ka mānoanoa o nā mea hoʻopili
(4)ʻO ka uhaki ʻana o ka huahana
a.ʻOi aku ka wela a i ʻole ka loaʻa ʻana o ka sulfur lōʻihi
b.ʻO ka nui o ka nui o ka mea vulcanizing agent
c.ʻAʻole pololei ke ʻano demolding
(5)Paʻakikī i ka hana
a.ʻOi aku ka maikaʻi o ka waimaka o ka huahana (e like me ke kiʻekiʻe tensile adhesive). Hōʻike ʻia kēia hana paʻakikī e ka hiki ʻole ke haehae i nā burrs
b.ʻAʻole maikaʻi ka ikaika o ka huahana, ʻike ʻia me nā ʻaoʻao brittle, hiki ke haehae i ka huahana
