一、Kuvandudzwa kweRotational Molding
Munyika dzekunze, kutenderera kuumbwa kwave kuri imwe yenzira dzinoshandiswa zvakanyanya epurasitiki kuumba. Mumakore ekuma1940, PVC paste yakashandiswa kugadzira matoyi akadai semabhora epurasitiki kuburikidza nekuumbwa kwekutenderera. Mumakore ekuma1950, iyo polyethylene rotational molding process ichishandisa yakaderera-density polyethylene poda resin seyakagadzirwa yakagadziridzwa kugadzira zvigadzirwa zvemaindasitiri zvakaita sematangi ekuchengetedza epolyethylene nemapombi makuru, ayo akakurudzira zvikuru kuvandudzwa kwekutenderera kwekuumbwa. Kubva ipapo, nylon, polycarbonate, ABS uye mamwe mapurasitiki akaumbwa zvakare nekutenderera kuumba maitiro. Pakazosvika makore ekuma1970, kuumbwa kwekutenderera kwakange kwave kuita hombe-hombe yekuumba epurasitiki.
Muna 1971, pakanga pane makambani anopfuura makumi mashanu akabatanidzwa mukugadzirwa kwezvinhu zvinotenderera zvekuumba muUK, uye vanenge makumi manomwe vanogadzira thermoplastics inotenderera; Kune makambani anodarika makumi maviri ari kuita basa rekutenderera rekuumba muEuropean continent, kusanganisira makambani anobva kuGermany, France, Switzerland, Norway, Austria, Denmark nedzimwe nyika.
Mukutanga kwema1970, UK yakakwanisa kupa roll molding machine inokwanisa kugadzira midziyo ine simba re18000L; Nyika yeNetherlands yakagadzira tangi hombe recylindrical rine dhayamita 2.1m uye kureba 4.8m. Tangi i 540kg uye kukora kwemadziro kuri 25mm. Muna 1970, huwandu hwese hwezvinhu zvinotenderera zvekuumba zvigadzirwa muEurope zvakasvika kupfuura 15000t, kusanganisira nezve 7000t muBritain.
Muna 1970, mayuniti anopfuura 500 muUnited States akabatanidzwa mukugadzirwa kwezvinhu zvinotenderera zvekuumba. Vaive vanopfuura 500inotenderera yekuumba michina, uye huwandu hwemidziyo inotenderera yekuumba yakanga yapfuura 10000 L (2400 magaroni); Iwo epamusoro epurasitiki zvikamu anogadzirwa nemuchina wekuumba roll ndeye 4.6× ina pfungwa nhanhatu× 2.1m.
Mumakore ekuma1960, kukurumidza kusimudzira tekinoroji yekuumba tekinoroji yaive yakabatana zvakanyanya nekuvandudzwa kwezvivakwa zveresin uye midziyo yekutenderedza. Munguva iyi, mapurasitiki akawanda akakosha ekuumbwa kwekutenderera akagadzirwa, senge PE P-320, Raychem Flamolin 771 uye mamwe ma polyethylene resin akagadzirwa neUnited Carburization Company. FE P-320 imhando yeyakadzika-density polyethylene, ine yakanaka kuyerera kuumbwa kwekuita kwepasi-density polyethylene resin uye yakaderera tembiricha inokanganisa kuoma, makemikari kuramba uye kusagadzikana kutsemuka kuramba kwepamusoro-density polyethylene resin; Raychems F1amo1in 711 is a cross-linked polyethylene resin yekutenderera kuumbwa. Pamusoro pekunge yakabatana-yakabatana, ine zvakare yekudzima midziyo. Iyo yakakurumbira roll molding cross-yakabatana polyethylene resin Marlex Cl-100 yePhilips yakagadziridzwawo panguva iyi.
Kuitira kuzadzisa zvinodiwa zvekugadzirira homberotational molding products, michina yakawanda inokwanisa kugadzira zvigadzirwa zvakakura zvinotenderera zvakagadziriswa mukupera kwema1960, iyo inogona kunyatsoshandisa nzvimbo yepasi uye kupisa simba. Muna 1970, inopfuura hafu yemichina yekuumba inotengeswa pamusika yaive nedhayamita inotenderera inodarika 1.75m. Uye zvakare, iyo yekudzora nhanho yemuchina yakagadziridzwa zvakare kune akasiyana madhigirii. Semuyenzaniso, iyo mitatu yemaoko inotenderera yekuumba muchina McNeil Auronismodel 3000-200 inogona kudzora kudziya uye kutonhora kutenderera kweruoko rumwe nerumwe, kuitira kuti zvigadzirwa zvehukuru hwakasiyana uye zvinhu zvigone kuumbwa panguva imwe chete. Kutenderera kwayo kunosvika 5m, uye huremu hwese hwefodya uye resin iyo ruoko rumwe runogona kutakura inenge 13500N; Iyo jekete mhando roll yekuumba muchina ine yakanaka yekupisa yekupisa mhedzisiro uye diki pasi nzvimbo yakagadzirwawo uye yakagadzirwa panguva ino.
Iko kuvandudza uye kutsvagisa kwekutenderera kuumbwa muChina kunogona zvakare kuteverwa kumashure kuma1960s. Pakazosvika makore ekuma1960, indasitiri yematoyi yeShanghai yakanga yatanga kushandisa nzira inotenderera yekuumba kuti ibudise zvinyoro zvePVC pellets gore negore; Chirimwa chechitatu cheShangsu Plastics chakabudirira kuyedza kugadzira 200L uye 1500L roll yakaumbwa polyethylene midziyo; Pakati pemakore ekuma1970, Beijing FRP Research Institute yakabudirira kugadzira chigadziko chenaironi chepurasitiki chinotenderera ndokuchiisa mumoto wesango nezvimwe zvigadzirwa. Nekudaro, iyo chaiyo yakakura-yakakura kugadzirwa kwemaindasitiri yakauya mushure mekutanga kwepamberirotational kuumbamidziyo uye tekinoroji kubva kunze kwenyika pakati uye mukupera kwema1980. Parizvino, yakakwanisa kugadzirira zvigadzirwa zvepurasitiki zvakakura senge matangi ekuchengetera makemikari ane mudziyo unopfuura 20000L uye mapurasitiki akakwirira ese epurasitiki yachts.
二、Kushandisa Rotational Molding
Nekuvandudza tekinoroji yekuumba tekinoroji, chiyero chekushandisa chezvinotenderedza zvigadzirwa zvekugadzira chakawedzera kuenderera. Kusvika ikozvino, kushandiswa kwezvinotenderera zvigadzirwa zvekuumba kwave kwakanyanya. Zvimwe zvikumbiro zvinomiririra zvinogona kuenzanisirwa sezvinotevera.
1. Zvikamu zvepurasitiki zvinotenderera zvemidziyo
Rudzi urwu rwezvigadzirwa zvepurasitiki zvinoshandiswa zvakanyanya mumatangi ekuchengetedza mvura, matangi emakemikari akasiyana emvura (akadai seasidhi, alkali, munyu, makemikari fetiraiza, mushonga wezvipembenene, nezvimwewo), midziyo yepeturu (matangi epeturu nematangi emafuta emotokari nendege), mabhomba ebhatiri, nezvimwe.
2. Zvikamu zvinotenderera zvemotokari
Iyo inonyanya kushandisa polyethylene uye polyvinyl chloride paste resin, uye roll inoumba akasiyana pombi fittings, senge air conditioning gokora, backrest, handrail, nezvimwe.
3.Midziyo yemitambo uye zvakasiyana-siyana zvinotsiva
Kune zvakanyanya akasiyana-siyana PVC paste roto akaumbwa zvikamu, senge polo yemvura, bhora rinoyangarara, bhasikoro chigaro cushion, chikepe chidiki uye chinobata chinovhundutsa pakati pechikepe nechiteshi. Iyo rotogrammed crosslinked polyethylene barrel yakagadzirwa kubva kuPhilips' rotogrammed crosslinked polyethylene muti "Maricxcl-100" inogona kukwikwidza nesimbi dhiramu, uye ine yakanaka makemikari kuramba uye mutengo wakaderera wekugadzirisa. Rotational palletizing tray yakatengeswa muUnited States, Japan nedzimwe nyika mukutanga kwema1970; Surfboards, mabhoti, nezvimwe zvakare zvikamu zvakaumbwa zvakaumbwa zvinowanzotaurwa mumabhuku.
4. Matoyi, modhi, mabasa emaoko, nezvimwe
Nekuti mold inotenderera inogona kugadzirwa nekukandira kwakaringana, electroforming uye mamwe maitiro; Kumusoro kwezvikamu zvinotenderera zvakaumbwa zvine "copy" yakanaka pahutano hwakanaka hwepamusoro pevhu rekugadzira mold. Naizvozvo, iyo inotenderera yekuumba nzira inogona kuita kuti zvigadzirwa zvive zvakapfava uye zvakanaka. Naizvozvo, inowanzoshandiswa kugadzira zvigadzirwa zvine kukosha kukuru kwekuona, kunyanyamatoyi, mhando, mabasa emaoko, nezvimwe.
5. Pamusoro pezviri pamusoro apa, panewo zvakasiyana-siyanamabhokisi, mabhomba, pombi hombe uye zvimwe zvigadzirwa zvinoshandiswa zvakanyanyarotational molding productssemabhokisi ekutengesa,magaba emarara, mateko emuchina, zvivharo zvekudzivirira, marambi, zvimbudzi, zvimbuzi, makamuri enhare, mayachts, nezvimwe.
Zvigadzirwa zvinotenderera zvekuumbwa zvakashandiswa zvakanyanya mukuchengetedza makemikari emvura uye kutakura, mabhizinesi emakemikari, maindasitiri ekuputira,kugeza matangiuye matangi ekuita mukugadzirwa kwepasi isingawanzo, pamwe nerwizi uyezvikepe zvegungwa, zvemumbamatangi emvuranemimwe minda.
