-Icandelo ezimbini lyu lweefomu: isishwankathelo, iimpawu kunye nohlolo

-Candelo ezimbini lyu i Polymer apho iveliswa ngokuxuba izithako ezimbini. I Isenzo isocyanate ezimbaxa, lo gama i-compound yesibini inokuba iqela hydroxyl. Iziqalelo basebenzisane, lo Polymer ngenxa amiliswe ukusuka kwisakhiwo lyu.

uhlobo lyu

Kuba Polymer kuya kufuneka ukuba ukuxuba arhente ayengawokuphilisa kunye nesiseko kwi olinganise efanelekileyo. Icandelo-Two lyu angamelwa ukutshintshatshintsha le polymerization ukubanda nobushushu. Le nkcazelo ukhetho yokugqibela kufuna sesichengeni lobushushu eziphezulu ngelixa eyayisakuba yi polymerized kwiqondo lobushushu yendalo.

iimpawu eziphambili

Izinto ezichazwe zisetyenziselwa ukwenza, aneempawu amandla phezulu, bona abanganyangekiyo bume ngolunya iimpembelelo eziyingozi, kwakunye kwamaqondo eziphakamileyo. Zonke ezi mpawu siyanda umda lokusebenzisa lyu. Kufanelekile ukuba ukwenziwa:

• ipeyinti;
• yokuncamathelisa;
• sealants;
• ivanishi.

Emva ukuxubana ekwakhiweni uzuza flowability kakhulu, nto leyo evumela ukuvelisa ngoko iindawo ekubunjweni ubugcisa. Umzekelo ukwabela amalungiselelo kwisingxobo. Kweli nqaku sithetha malunga candelo-ezimbini lyu ngodongwe esiXhoseni. Le propati eziphathekayo zigqitywa ngamacandelwana yokuqala. Kule inxalenye ebalulekileyo hardener isocyanate ubuvuvu.

iimpawu ezongezelelweyo

Iimpawu ezibonakalayo zisenokwahluka ngokuxhomekeke ngokongeza izinto ezahlukeneyo, ezifana fillers kunye nedayi. Ezinye polyurethanes zithatha indawo irabha, ngokuba esibonakala okubuyela kwimo ephezulu. Polyurethanes zingafunyanwa ukuba unako ukubuyisela isimo yayo yoqobo ngenxa umonakalo, nto leyo ebenza ingakumbi ezixabisekileyo kolu shishino.

Ezondawo sebenzisa

Ezimbini-component lyu wafumana ngokubanzi namhlanje. Amanqaku esetyenziselwa ukwenziwa izacholo, iindlela ezahlukeneyo kunye castings amagiya. Iimpawu zokusebenza iinxalenye onesiphumo kakhulu phezulu. Oku kuvumela ukusetyenziswa eziphathekayo kwiimeko ezinzima. Ngenxa yoko, akakwazi ukuthenga amacandelo viscous, nzima afana ukumelana. Njengoko lo wokugqibela ube:

• elabiwe;
• imithi;
• pulleys;
• amavili;
• roller;
• wazithengisa unamazinyo;
• uphawu izinto;
• Ipeyinti protective Various;
• clutch;
• imibhobho;
• Iinkcukacha iibheringi;
• kwisingxobo.

Iinkcukacha bazimisele ukuba abe esemgangathweni ophezulu elide, ngenxa yokuba ukumelana ukunxiba kwaye ixesha elide kakhulu. Icandelo-ezimbini elastic iifom lyu Ulwelo isiseko amasondo for iilori forklifts. Ngenxa yoko, njani imveliso zingafumaneka, nto leyo kakhulu ixesha elide kakhulu ngerabha. Bakulungele ukusebenza kwanaxa umonakalo enilinyatheleyo.

Le nto sisiseko axhasayo isikhokelo izileyi, leyo ezisebenza ngokudibene ibhanti yokuthutha kunye swa. Iziqalelo bakulungele ukukhonza elide kakhulu kunokuba irabha ibhanti transmission, imizila namaculo.

Izinto ezisetyenziselwa osisidambisi kunye izinto uphawu, kuba siyakwazi ukumelana ephakamileyo ukunxiba elide. Kungenxa yoko le nto izahlulo zerabha kwiminyaka yakutshanje ngakumbi yaye ngokufuthi ngakumbi esikhundleni lyu. Ukuba nokwenzeka kulo mzekelo uhlala kwinqanaba elifanayo. Icandelo-Two lyu yokubumba ifumene isicelo ekwenziweni kwemibhobho, obubonakala ngokuba ngamandla kunye nokumelana imichiza. Izinto wafumana enye. Ngaphezu koko, usebenzisa izinto akakwazi kuphela ukukhusela lwemibhobho ukusuka ngaphakathi, kodwa ngaphandle.

Izimvo kwemimandla owongeziweyo wokusetyenziswa

Ngokutsho kubathengi,-candelo ezimbini lyu isetyenziswa kwimveliso yokuncamathelisa ipeyinti kunye ivanishi. Lo mxube afunyenwe emva polymerization ukumelana iimpembelelo yangaphandle, siqine yaye ukulungele ukukhonza ixesha elide. Le lyu ulwelo isetyenziswa ngakumbi ekwenziweni iifomu, nto leyo yenziwa ngokwenza technology. Emva koko, ezi mveliso zisetyenziswa ekubunjweni:

• eziphathekayo;
• emahlamvini ipholiyesta;
• Yanjengomthwebeba;
• gypsum.

Ukususela amazwi abathengi, lulwelo icandelo-ezimbini lyu isetyenziswa nayo kwinkalo amayeza, apho izinto sisiseko amazinyo. Lyu esetyenziswa rhoqo nezacholo iimveliso. Kulo nga imigangatho bade kuphalala, obubonakala ngokuba ixesha elide, ukumelana ukunxiba kunye nokumelana eliphezulu imithwalo.

Ngokutsho kubathengi kwezinye iindawo iindawo lyu kunabanye for eziliqela parameters. Nangona kunjalo, inkqubo yokuvelisa kulula kakhulu, nto leyo evumela ukuba kumnyama imveliso lwamacandelo omncinane kunye castings ezinkulu, owokuqala apho inokuba akukho ngaphezu kokuba gram, ngeli lixa babe kubunzima obuyi 500 kg nangaphezulu.

Ukuze ufumane inkcazelo engakumbi lyu ezibolile

-Icandelo ezimbini lyu ngokwenza ngumngundo ungakwazi ukumelana inani elithile castings. Ukuba sithetha izitampu eziqhelekileyo, Yamxuluba ngamatye ukuba amaxesha ubuncinane 1,200 wenziwe. Ukuba inkqubo ifomu yemveliso wasebenzisa ezingcono kunye neemfuno soqulunqo umxube iphunyeziwe, ngoko ke Ifomu bakulungele ukumelana ukuya ku-4000 castings. Oku kunjalo kuba xa imilo siqinisekiswe ngu-processing lwepolitiki, kwakunye esetyenziselwa zokuzaliswa ayikho esirhabaxa kakhulu, bako kunye nezinto kwakuse.

Bona uluhlu kwimarike yamazwe ngamazwe, unako ukuqonda ukuba lyu namhlanje simelwe yemiyinge eziliqela, kandziyisa phakathi kwabo:

• vulkopreny;
• Vulkollan;
• adipreny;
• poramoldy.

Ukuba ukhetha lophawu Russian, kufuneka ukhethe i SIC-DB 5, SKU-PFL-100. Yakhiwa ipholiyesta imveliso yasekhaya, kodwa umgangatho ayikho mbi kunoogxa babo amazwe. Ngaphezu koko, ke besiya kwezinye iinkalo.

Brand lyu kwahluka kumafa kwemichiza, isixa amaqela urethane, ulwakhiwo amatyathanga Polymer kunye nezinto ubunzima eziphilayo. Izinto zobumnini ungalawuleka Ukukhetha ngenyameko izinto ekrwada. Isiphumo zingafumaneka ingxubevange kunye neepholimazi chain branched.

Kwezithako lweefomu lyu

-Icandelo ezimbini lyu lweefomu zingahlonyelelwa zizinto ezahlukeneyo, ezizezi:

• modifiers;
• fillers;
• nedayi.

na Kwakufuneka ukuphucula umgangatho nokwakheka. Umzekelo, ukuba ukukhawulezisa indlela eyiyo yebug kwaye zisetyenziswa, nelo oonina ezincinane. Ngokubhekiselele zombala, bayakwazi ukutshintsha ekukhangelayo indlela element yokukhuza umbala. Ukwenzela ukunciphisa isiqulatho zeplastiki, fillers zisetyenziswa evumela iimveliso ngaphezulu kwaye sitshiphu.

Excipients kungaba:

• talc;
• ngetshokhwe;
• carbon omnyama;
• okuzenzela imichiza, iglasi, carbon.

Noko ke, le ludwe ingqalelo epheleleyo. ifomu lyu namatye babe abangasekhoyo umbala ukusuka mthubi kukukhanya esimdaka. Ukuba ukusetyenziswa kwezithako ezizodwa, kunokwenzeka ukuba phantse nawuphi na umbala.

isiphelo

Polyurethanes namhlanje sele isetyenziswe phantse kuzo zonke iinkalo zoshishino. izinto Okuninzi isetyenziswa kubomi bemihla ngemihla. Njengoko enye yeendawo ezithembisayo izenzo ulwelo bicomponent lyu. ukusetyenziswa kwaso kube lula yaye ikhawuleziswe umsebenzi ukulahlwa eziphathekayo, ityatyekwe. Ngoncedo lwe lyu wenza ukuba imveliso iifomu ezincinane bokwakha, ukupheyiva kunye nezinto zokuhombisa, nokuba ekhaya.
