Akuyika amatha kuumba silikoni: zida. Zingalowe m'malo akuponya nkhungu wa silikoni

Kupanga pang'ono preforms pulasitiki ambiri amangoti ntchito zingalowe akuyika amatha kuumba silikoni. Njira zimakhalanso ndalama (zotsimikizira zitsulo nkhungu kumafuna kuchuluka akuluakulu onse nthawi ndi ndalama). Komanso, amatha kuumba silikoni ntchito mobwerezabwereza, komanso kwambiri amachepetsa mitengo ya zinthu.

akamaumba pulasitiki

Akamanena za kuponyera njira za pulasitiki ndi motere. Nkhani chopangidwa ndi chitsulo chosungunula mu unit wononga (zipangizo zina zapadera kwa akuyika amatha kuumba silikoni). Mchikakamizo cha unyinji wa upita pisitoni pamodzi wothamanga, ndiyeno chimadzaza danga la nkhungu. Kotero inu mukhoza kutenga kuponya. Pamene usavutike, maatomu pulasitiki umene tichipeza, anayamba kusunthira mosintha ndi mwachisawawa. Komabe anayamba kupanga pa yozizira malo crystallization. Pa makoma muchikombole galasi kukula amene akupezeka, kenako ndondomeko chimachitika mu kuponya. Pa nthawi imeneyi n'kofunika kwambiri kusunga zinthu kutentha, kusankha olondola padzuwa nthawi. Mu mapulasitiki ena akamaumba silikoni nkhungu adzakhala khalidwe osauka, ndi kuda owoneka a ukwati. Koma pamwamba pa zonsezi, tiyenera mitundu okha, ndi amene misa udzatsanulidwa pa crystallization.

polenga mitundu kwa luso kuponyera

Pali njira zingapo kulenga amatha kuumba silikoni. The oyamba - ndi kuponyera olimba. Njira imeneyi ndi yabwino chifukwa chopanga losavuta: ziboliboli, kachikumbutso kupanga awiri, ooneka enieni mbali. Lachitsanzo aikidwa mu nkhungu, wodzazidwa ndi silikoni. mitundu Releasable anapangidwa ngati yapita amodzi, ntchito mosiyanasiyana zovuta zambiri. Mbali ziwiri nkhungu amapangidwa mu magawo angapo. Choyamba, zoyambirira za akusowekapo ladzala, pambuyo kuchiritsa silikoni kukalowa mawonekedwe ndi gawo lachiwiri anapanga chimodzimodzi. wofunika kwambiri pano njira yochokera tisonyezeni maloko wapadera (kuumba ndi silikoni mawonekedwe a mtundu uwu atenge malo opanda kusamutsidwa ake). Apafupi kwambiri amatsatira mfundo akusowekapo mawonekedwe onse "mu kumafalikira." Pa chidutswa ndi burashi kuti ntchito silikoni mwachilungamo viscous. Dongosololi chikuchitika mu magawo angapo, m'pofunika kuti kubwereza lathunthu la zina zabwino ka mankhwala. Pankhaniyi, mawonekedwe palokha ndi woonda kwambiri - 3mm. Kuti iye anali atagwira mawonekedwe mu chomaliza amalenga kunja chipolopolo zovuta.

Silicones kupanga amatha kuumba

Zingalowe kuponyera mu amatha kuumba silikoni zimaphatikizapo kugwiritsa ntchito zosiyanasiyana kulenga mawerengetsedwe. Mmodzi wa iwo - monga silikoni Nkhungu Star. Izo ntchito kukhuta olimba, ndi mokwanira amphamvu mofewa. Akuchiritsa chikuchitika firiji. Pakuti njira "mu chafalikiradi" Nthawi zambiri ntchito mndandanda wa Rebount. silikoni uyu ali ndi kukhuthala lalitali, sipangakhalenso ankalamulira kudzera thickener ndi. Akuyika amatha kuumba silikoni wa mtundu uwu limachititsa kupeza apamwamba, masanjidwewo olimba, ndi moyenera, mkulu-mwatsatanetsatane mwatsatanetsatane. Palinso theka-mandala silicones, amene ali abwino kwa mitundu kugawanika.

Zipangizo kuponyera

Monga ulamuliro, kwa opanga mbali ntchito okha polyurethane. Mabukuwa ali mkulu zimakhudza mphamvu, kuuma, elasticity. amadwala kulimba kwamakokedwe, kuichotsa adzalandira polyurethane mphira. ntchito zawo kupanga zosiyanasiyana zomangirazo, zonenepa, masitampu, gaskets, bushings. Ndipo ngakhale ntchito kuumba pulasitiki mandala. Iye kugonjetsedwa kwambiri UV cheza ndi kupitiriza kusamala chilungamo chake pamene penti. Mbali - .. magalasi mayesero osiyanasiyana, prototypes mankhwala, kupanga aways, etc. Childs, mawonekedwe silikoni akamaumba zimaphatikizapo kugwiritsa ntchito zosakaniza ziwiri zikuluzikulu, monga mapulasitiki ndi mwachindunji chothandizira.

kuponyera pulasitiki amatha kuumba silikoni. zida

Ang'ono-ang'ono yopanga billets osewera - ndi ndondomeko kuti amalola kuti mtanda replicas mbali cha kapangidwe iliyonse. Nthawi zambiri, njira kuti apange prototypes amene anayesedwa musanayambe kupanga siriyo, akamaliza maonekedwe kamangidwe.

Industrial akamaumba pulasitiki mu zida silikoni nkhungu amapereka: m'chipinda zingalowe (jekeseni akamaumba makina), uvuni, zingalowe chosakanizira (chosakanizira). Silikoni poyamba anakonza mu chipinda zingalowe, kumene zinthu degassing ndondomeko. Izi ndi kuteteza mapangidwe thovu mawonekedwe. Kamodzi mawonekedwe chakhala kuponyera ndi preheated, wosakaniza yomweyo polyurethanes (kapena resins kwa chigawo chomaliza). ndondomeko izi zimachitika mu chipinda kuyamwa. Osakaniza unatsanuliridwa mwa sprue mu nkhungu. Pakuti chomaliza processing zofunika preform anaikidwa uvuni wapadera, kumene solidification chomaliza cha mankhwala pa kutentha 70 ° C.

Zingalowe m'malo chipinda. Features Ofunika

Childs, kupanga sikelo ntchito kuponyera basi mu amatha kuumba silikoni. Zida, ndicho m'chipinda zingalowe, ndipo amalola kulamulira kutentha ndi kuponyera liwiro. The woyendetsa sikutanthauza luso ndi nzeru, monga kulamulira lachokera ku opaleshoni dongosolo, amene ali ndi zodziwikiratu ndi Buku kusinthitsa. Pali mwayi ndi kusintha pulogalamu anasankha. zosintha zosiyanasiyana m'zipinda preform angathe kubala mpaka 5 kg (mwachitsanzo, kamera cha ku Switzerland-02). Unsembe okonzeka ndi chikepicho kukweza zisamere pachakudya silikoni. Dziwani kuti dongosolo la cha ku Switzerland-02 angagwiritsidwe ntchito ngati masanjidwewo ang'ono ndi kulemedwa kwambiri.

Njira ina - MCP kamera. The zipangizo akuponya mu nkhungu silikoni limachititsa kutulutsa mbali ndi makoma woonda ndi kasinthidwe zovuta. ndondomeko Ichi ndi chifukwa vuto masiyanidwe. Ndiye, kuponyera chifukwa atachotsedwa, ndipo kenako izo solidifies mu mlengalenga. Zingalowe kuponyera mu amatha kuumba silikoni ena mitundu ya mapulasitiki udzatha mu ng'anjo kupereka yunifolomu Kutentha za mlengalenga, motero workpiece.

Final billets processing pulasitala

Pambuyo misa pulasitiki solidifies kwathunthu, izo mosamala kuchotsedwa nkhungu. Kumachitika Machining padziko, ndi kuwavula ndi kuchotsedwa protrusions ali pansi monyanyira. Ngati anakhumba preform ndi lokutidwa kapena utoto kapena zinthu zina zodzitetezera. Ayenera kutsukidwa ndi silikoni nkhungu, kuchotsa pulasitiki owonjezera. Ndiyeno kuchapa akukonzekera ntchito wotsatira. Tikumbukenso kuti pulasitiki akamaumba silikoni nkhungu ikukhudza ntchito mobwerezabwereza kwa mawerengetsedwe (nthawi 20 80).

Ubwino waukulu njira

kupanga ang'ono-ang'ono kusiyana pompopompo, zikhoza qualitatively kuwunika msika, kuyesa mankhwala kulenga ntchito yapadera olemba mu pang'ono. amatha kuumba silikoni kuti ntchito akamaumba jekeseni, analola kuti athe kutengera kapangidwe, mawonekedwe, kapangidwe preform. Mwatsatanetsatane mosavuta anamasulidwa masanjidwewo ndi zomwe zingagwiritsidwe ntchito mobwerezabwereza. Castings ndi mlingo wa zolakwa zoonekeratu, akadakwanitsira thupi ndi makina katundu. Komanso, nthawi zina, ngakhale silikoni nkhungu zitsulo akhoza adzakhetsedwa.

Koma mwayi waukulu umene adaponya mwa amatha kuumba silikoni - mtengo. Ogulitsa utumiki limasonyeza kuti mtengo chomaliza cha preform kudzadalira nkhani pulasitiki ndi zinthu zambiri ku magawo (mwachitsanzo, kukula kwa akusowekapo 10 10 10 cm kungakudyereni 1500 rubles). Silikoni yokha zikhoza kugulidwa ku rubles 500 pa kilogalamu, pulasitiki - kuchokera 700 rubles. Mtengo wa amatha kuumba zitsulo ndi mkulu mokwanira pa nthawi kugwiritsa ntchito iwo mophweka sizithandiza (ngati kufalitsa mayunitsi angapo). A yabwino silikoni masanjidwewo ndi ntchito kunyumba, kugula zipangizo zodula kapena zapamwamba Sikuti. Munthu akhoza kungowauzira kuchita mawonekedwe awo, kuganizira moyo polyurethanes (nthawi imene kukhala madzi ndi oyenera kuthira), kutsatira mfundo zina zabwino zonse zamakono - ndi akuyika amatha kuumba silikoni ngakhale kunyamula kunyumba. Malinga anapezazo, mtengo wa preform mu nkhani pano - za 70-140 rubles.
