一、Ka hoʻomohala ʻana oHoʻowili ʻia
I nā ʻāina ʻē, ʻo ka rotational molding kekahi o nā kaʻina hana hoʻoheheʻe plastic i hoʻohana nui ʻia. I ka makahiki 1940, ua hoʻohana ʻia ka pāpaʻi PVC e hana i nā mea pāʻani e like me nā pōpō plastik ma o ka hoʻowili ʻana. I ka makahiki 1950, ua hoʻomohala ʻia ke kaʻina hana hoʻoheheʻe polyethylene rotational e hoʻohana ana i ka resin polyethylene pauka haʻahaʻa haʻahaʻa ma ke ʻano he mea maka no ka hana ʻana i nā huahana ʻoihana e like me nā pahu mālama polyethylene a me nā paipu nui, ka mea i hoʻoikaika nui i ka hoʻomohala ʻana i ke kaʻina hana rotational. Mai ia manawa, ua hoʻoheheʻe ʻia ka nylon, polycarbonate, ABS a me nā plastics ʻē aʻe e ke kaʻina hana hoʻololi. I nā makahiki 1970 mua, ua lilo ka hoʻoheheʻe ʻana i ka hoʻoheheʻe ʻana i mea hoʻoheheʻe nui.
Ma 1971, ua ʻoi aku ma mua o 50 mau hui i hana i ka hana ʻana i nā huahana rotational molding ma UK, a ma kahi o 70 mau mea hana o rotational molding thermoplastics; ʻOi aku ma mua o 20 mau ʻoihana e hana ana i ka hoʻoheheʻe ʻana i ka rotational molding ma ka ʻāina ʻEulopa, me nā hui mai Kelemania, Farani, Switzerland, Norewai, Austria, Denmark a me nā ʻāina ʻē aʻe.
I nā makahiki 1970 mua, ua hiki i ka UK ke hoʻolako i kahi mīkini'ōwili'ōwili i hiki ke hana i nā pahu me ka mana o 18000L; Ua hana ʻo Netherlands i kahi pahu cylindrical nui me ke anawaena o 2.1m a me ka lōʻihi o 4.8m. He 540kg ka pahu pahu a he 25mm ka mānoanoa o ka pā. I ka makahiki 1970, ʻoi aku ka nui o ka nui o nā huahana molding rotational ma ʻEulopa ma mua o 15000t, me kahi o 7000t ma Beretania.
I ka makahiki 1970, ʻoi aku ma mua o 500 mau ʻāpana ma ʻAmelika Hui Pū ʻIa i hana i ka hana ʻana i nā huahana hoʻoheheʻe rotational. Ua ʻoi aku lākou ma mua o 500mīkini hoʻoheheʻe rotational, a ua ʻoi aku ka nui o nā ipu hoʻoheheʻe rotational ma mua o 10000 L (2400 galani); ʻO nā ʻāpana plastik kiʻekiʻe loa i hana ʻia e ka mīkini ʻōwili ʻōwili he 4.6× ʻehā helu ʻeono× 2.1m.
I ka makahiki 1960, ua pili loa ka hoʻomohala ʻana o ka ʻenehana hoʻoheheʻe rotational i ka hoʻomaikaʻi ʻana i nā waiwai resin a me nā mea hana hoʻoheheʻe rotational. I loko o kēia manawa, ua hoʻomohala ʻia nā plastics kūikawā no ka hoʻoheheʻe ʻana, e like me PE P-320, Raychem Flamolin 771 a me nā resins polyethylene ʻē aʻe i hoʻomohala ʻia e United Carburization Company. ʻO FE P-320 kahi ʻano polyethylene haʻahaʻa haʻahaʻa, nona ka hana hoʻoheheʻe maikaʻi ʻana o ka resin polyethylene haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ke kūpaʻa kemika a me ke koʻikoʻi ʻana i ke kūpaʻa o ka resin polyethylene kiʻekiʻe; ʻO Raychems F1amo1in 711 kahi resin polyethylene i hoʻopili ʻia no ka hoʻowili ʻana. Ma waho aʻe o ka hoʻopili ʻia ʻana, loaʻa iā ia ka waiwai hoʻopau iā ia iho. Ua hoʻomohala ʻia ka ʻōwili roll kaulana i hoʻopili ʻia i ka polyethylene resin Marlex Cl-100 o Philips i kēia wā.
I mea e hoʻokō ai i nā pono o ka hoʻomākaukau nuinā huahana hoʻoheheʻe rotational, ua kūkulu ʻia nā mīkini he nui i hiki ke hana i nā huahana molding rotational nui i ka hopena o 1960s, hiki ke hoʻohana pono i ka papahele a me ka ikehu wela. I ka makahiki 1970, ʻoi aku ma mua o ka hapalua o nā mīkini hoʻoheheʻe ʻōwili i kūʻai ʻia ma ka mākeke i ʻoi aku ke anawaena rotary ma mua o 1.75m. Eia kekahi, ua hoʻomaikaʻi ʻia ka pae mana o ka mīkini i nā pae like ʻole. No ka laʻana, hiki i ka mīkini hoʻoheheʻe ʻekolu lima ʻo McNeil Auronismodel 3000-200 ke hoʻomalu i nā pōʻai hoʻomehana a me ka hoʻoluʻu o kēlā me kēia lima i kahi kaʻawale, i hiki ke hoʻoheheʻe ʻia nā huahana o nā ʻano nui a me nā mea waiwai i ka manawa like. ʻO kona anawaena rotary a hiki i 5m, a ʻo ka nui o ke kaumaha o ka mold a me ka resin e hiki ai i kēlā me kēia lima ke amo ma kahi o 13500N; Ua hoʻolālā ʻia a hana ʻia ka mīkini hoʻoheheʻe ʻana o ka lole me ka hopena wela maikaʻi a me kahi papahele liʻiliʻi i kēia wā.
Hiki ke huli ʻia ka hoʻomohala ʻana a me ka noiʻi ʻana o ka hoʻoheheʻe ʻana o ka rotational ma Kina i nā makahiki 1960. Ma ka hopena o nā makahiki 1960, ua hoʻomaka ka ʻoihana pāʻani o Shanghai e hoʻohana i ke ʻano hoʻoheheʻe rotational e hana i nā pellet PVC palupalu i kēlā me kēia makahiki; ʻO ke kolu o ka mea kanu o Shangsu Plastics i hoʻāʻo maikaʻi i ka 200L a me 1500L roll molded polyethylene ipu; Ma ka waena waena o 1970s, ua hoʻomohala maikaʻi ʻo Beijing FRP Research Institute i ka pahu nylon plastic rotational a hoʻohana ʻia i nā mea kinai ahi a me nā huahana ʻē aʻe. Eia naʻe, hiki mai ka hana ʻoihana nui maoli ma hope o ka hoʻokomo ʻana o nā mea kiʻekiʻehoʻowili ʻananā lako a me nā ʻenehana mai nā ʻāina ʻē i ka waena a me ka hopena o 1980s. I kēia manawa, ua hiki iā ia ke hoʻomākaukau i nā huahana plastik nui e like me nā pahu mālama kemika me ka nui o ka pahu i ʻoi aku ma mua o 20000L a me ka plastic kiʻekiʻe nā yacht plastik āpau.
二
Me ka hoʻomohala ʻana o ka ʻenehana molding rotational, ua hoʻonui mau ʻia ka laulā noi o nā huahana rotational molding. A hiki i kēia manawa, ʻoi aku ka nui o ka hoʻohana ʻana i nā huahana rotational molding. Hiki ke hōʻike ʻia kekahi mau palapala noi e like me kēia.
1. Nā ʻāpana plastic rotational no nā ipu
Hoʻohana nui ʻia kēia ʻano huahana i loko o nā pahu mālama wai, nā pahu no nā kemika wai like ʻole (e like me ka waikawa, ka alkali, ka paʻakai, nā mea kanu kemika, pesticide, a me nā mea ʻē aʻe). nā pūpū pākaukau, etc.
2. Nā ʻāpana hoʻololi no nā kaʻa
Hoʻohana nui ia i ka polyethylene a me ka polyvinyl chloride paste resin, a me ka ʻōwili ʻana i nā ʻano paipu like ʻole, e like me ka ea air conditioning elbow, backrest, handrail, etc.
3.Nā lako haʻuki a me nā mea pani like ʻole
Nui nā ʻāpana i hoʻoheheʻe ʻia ʻo PVC paste roto, e like me ka polo wai, ka pōpō lana, ka noho kaʻa kaʻa, ka waʻa liʻiliʻi a me ka mea hoʻoheheʻe i waena o ka moku a me ka pā. ʻO ka pahu polyethylene i hoʻopaʻa ʻia i loko o lokogrammed i hana ʻia mai ka lāʻau polyethylene i hoʻopili ʻia ʻo Philips "Maricxcl-100" hiki ke hoʻokūkū me ka barela metala, a he kūpaʻa maikaʻi kona kūpaʻa a me nā kumukūʻai mālama haʻahaʻa. Ua kūʻai kūʻai ʻia ka pā palletizing rotational ma ʻAmelika Hui Pū ʻIa, Iapana a me nā ʻāina ʻē aʻe i nā makahiki 1970 mua; ʻO nā papa heʻe nalu, nā waʻa, a me nā mea ʻē aʻe he mau ʻāpana i ʻōwili ʻia i ʻōlelo pinepine ʻia ma ka palapala.
4. Nā mea pāʻani, nā mea hoʻohālike, nā mea hana lima, etc
No ka mea hiki ke hana ʻia ka mold rotational e ka hoʻolei pololei ʻana, electroforming a me nā kaʻina hana ʻē aʻe; ʻO ka ʻili o nā ʻāpana i hoʻoheheʻe ʻia he hopena maikaʻi "kope" i ka hoʻolālā maikaʻi o ka ʻili o ka lua mold. No laila, hiki i ke ʻano hoʻoheheʻe rotational ke hana i nā huahana a nani loa. No laila, hoʻohana pinepine ʻia e hana i nā huahana me ka waiwai nānā nui, ʻoi akumea pāʻani, nā hiʻohiʻona, nā mea hana lima, etc.
5. Ma waho aʻe o nā mea i luna, aia kekahi mau ʻano like ʻolepahu, nā pūpū, nā paipu nui a me nā huahana ʻē aʻe i hoʻohana nui ʻia nonā huahana hoʻoheheʻe rotational, e like me nā pahu hoʻololi,nā ʻōpala, nā pūpū mīkini, nā uhi pale, nā pale kukui, nā lumi ʻauʻau, nā halepaku, nā lumi kelepona, nā moku moku, etc.
Ua hoʻohana nui ʻia nā huahana molding rotational i ka mālama ʻana i nā kemika wai a me ka lawe ʻana, nā ʻoihana kemika, ka uhi ʻenehana,nā pahu holoia me nā pahu hoʻoheheʻe i ka hoʻomākaukau ʻana o ka honua, a me ka muliwai a menā holo moana, hale nohopahu waia me nā kula ʻē aʻe.
