Two-chinoumba polyurethane kuti siyana: muchidimbu, zvinhu uye wongororo

Two-chinoumba polyurethane chinhu polymer riri zvinoberekwa nokusanganisa pakugadzira maviri. Wokutanga chiito isocyanate remubatanidzwa apo mukomboni yechipiri inogona kuva hydroxyl boka. The okunze dyidzana, kunoguma polymer achiumbwa kubva polyurethane mamiriro.

polyurethane marudzi

Nokuti polymer zvinoda kusanganisa okurapa mumiririri uye chawo ari zvakakodzera kukura. Two-chikamu polyurethane anogona hunomiririrwa kusiyana kwechando uye kupisa polymerization. Zvapedzisira Ipfungwa zvinhu zvinoda kugara tembiricha yakakwirira apo vaimbova iri polymerized panguva dzinongoitika tembiricha.

Key zvinhu

The zvinorondedzerwa zvinhu zvinoshandiswa kuumbika, ave simba unhu, ivo husingakwanisi mamiriro ezvinhu akaoma uye zvinokuvadza, uyewo akakwidziridzwa tembiricha. All idzi vari kuwedzera kukura kwebasa kushandiswa polyurethane. Zvakakodzera pagadzirwe:

• pendi;
• adhesives;
• sealants;
• varnishes.

Mushure nokusanganisa murwiyo anowana wakanaka flowability, izvo zvinoita kuti kugadzira kwazviri pagondobwe vachikanda rwokugadzira. Muenzaniso ndiko govera ruoko zvirongwa. Munyaya ino tiri kutaura pamusoro maviri chinoumba polyurethane Kudzingwa mhando. The zvokunyama ehupfumi takatsunga ne chepakutanga zvinoriumba. In ichi chinokosha isocyanate hardener nechigadziko.

mamwe zvinhu

The zvokunyama ehupfumi dzingasiyana zvichienderana kuwedzera akasiyana zvinhu, zvakadai fillers uye madhayi. Vamwe polyurethanes kutsiva rabha, nokuti mukuru elasticity inozivikanwa. Polyurethanes anogona kuwanikwa kuti vari kudzorera yaro yepakutanga chimiro nokuda zvokuimba kukuvadza, unoita kuti kunyanya anokosha ari indasitiri.

Overview nzvimbo kushandiswa

Two-chinoumba polyurethane akawana kwakapararira nhasi. Material rakashandiswa kugadzirwa zvishongo, akasiyana zvigadziriswe uye castings rachulis. Chokupika ehupfumi ari zvichizoita zvikamu zviri kumusoro chaizvo. Izvi zvinobvumira kushandiswa kwemashoko kunyange utsinye ezvinhu. Somugumisiro, asingagoni kuwana viscous, zvakaoma uye mishonga nemishonga zvinoriumba. Sezvo yokupedzisira angava:

• giya;
• miti;
• pulleys;
• mavhiri;
• rollers;
• toothed mabhandi;
• Simbiso zvinhu;
• Various unodzivirira coatings;
• batira;
• mapaipi;
• Details of mabheyaringi;
• ruoko.

Details vanoda kuva yepamusoro uye refu, nokuti husingakwanisi kupfeka uye vari zvikuru vafuke. Liquid maviri-chikamu kwakavharwa nenyama polyurethane marudzi hwaro engoro kuti motokari uye forklifts. Somugumisiro, chigadzirwa kunogona kuwanikwa, iro zvikuru yakasimba kupfuura rabha. Vakagadzirira kushanda kunyange kana kukuvara musvine.

The acho ndiyo hwaro hwokutsigira uye muperekedzi rollers, izvo wakashanda pavanoparidza conveyor bhandi uye conveyor. The zvinhu zvagadzirwa kushumira yakareba kupfuura rabha bhandi yedzimudzangara, makwara uye makwara.

Mashoko akashandiswa damper uye chisimbiso okunze, nokuti ane yepamusoro nemishonga kupfeka uye mukurumari. Ndokusaka rabha zvikamu mumakore achangopfuura uye kakawanda ne polyurethane. Kuchinja mu iyi inoramba nenguva chechetere. Two-chikamu polyurethane Kuumbwa awana chikumbiro ari zvaAtemisi nyere, izvo nesimba uye nemakemikari nemishonga inozivikanwa. Zvinhu zviri kuwanikwa mune chimwe. Uyezve, kushandisa zvinhu haagoni kudzivirira chete mapaipi kubva mukati, asi kunze.

Reviews mimwezve nzvimbo kushandiswa

Maererano vatengi, mbiri-chinoumba polyurethane rinoshandiswa pagadzirwe adhesives uye pendi uye varnishes. Musanganiswa vakawana pashure polymerization husingakwanisi zvokunze ekushandiswa, zvakasimba yakaitwa uye akagadzirira kushumira kwenguva refu. The mvura polyurethane rinoshandiswa kunyanya kugadzirwa siyana, izvo anoitwa zvokukanda rwokugadzira. Naizvozvo, zvinhu izvi zviri kushandiswa rekukuputsirai:

• kongiri;
• polyester Inogadzirwa nemasiridzi anobuda mumiti;
• wakisi;
• gypsum.

Kubva mashoko vatengi, imvura maviri-chikamu polyurethane rinoshandiswa zvakare mune zvokurapa, apo mashoko ndiyo hwaro dentures. Polyurethane rinoshandiswa kakawanda uye zvishongo mukugadzira. Kubva ichi chinogona kunyange uchidururwa uriri, ayo kuburikidza yakasimba, nemishonga dzinoratidzwa kupfeka uye yakakwirira nemishonga kuti mitoro.

Maererano vatengi mune dzimwe nzvimbo polyurethane zvikamu zviri nani kupfuura simbi wandei parameters. Zvisinei, kugadzira muitiro zviri nyore zvikuru, izvo zvinoita kuti vawane panguva goho ose maduku zvinoriumba uye hombe castings, okutanga anogona kuyera hapana kupfuura giremu, ukuwo yokupedzisira vangava guru kg 500 uye kupfuura.

Kuti uwane mamwe mashoko pamusoro polyurethane kuti achitanga

Two-chinoumba polyurethane yokuita anoumba angakudzivisai imwe nhamba castings. Kana tiri kutaura pamusoro zvavo inoratidza kuti chakakandirwa mabwe anogona kuitwa kanenge 1,200 nguva. Kana muitiro okuwana fomu vakashandisa akanakisisa zvinhu uye zvinodiwa achigadzirira musanganiswa kunge akasangana, ipapo chimiro achava vakagadzirira kupikisa kusvikira 4,000 castings. Izvi ndezvechokwadi kunyange zvakadaro kana chimiro hwakasimbiswa nokuda Vacuum kubudiswa, uyewo zvinoshandiswa zvekupfakira hakusi hasha kwazvo, kungatikanganisa uye namira zvokuvakisa.

Ona siyana mumusika dzakawanda, unogona kunzwisisa kuti polyurethane nhasi chinomiririrwa pezvitsiga akawanda, pfungwa pakati pavo:

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

Kana uchida munhu Russian muchiso, unofanira kusarudza SIC-PU 5, SKU-PFL-100. Ivo akagadzirwa polyester wechipfuwo kugadzira, asi unhu haasi kupfuura zvavo dzimwe dzomuzana. Uyezve, vari kutungamirira mune zvimwe zvinhu.

Brand polyurethane zvisingapindirani makemikari anoumba, uwandu mapoka urethane, kuvakwa polymer ngetani uye samolecular uremu zvinhu. Properties anogona tungamirwe kunyatsosarudza kuti mbishi zvinhu. Zvinogona kuwanikwa chiwanikwa uye mapazi cheni Polymers.

Yokuvirisa nokuti polyurethane siyana

Two-chinoumba polyurethane kuti siyana vanogona vaisanganisa nokuda siyana zvinhu, zvinoti:

• modifiers;
• fillers;
• Dhayi.

Vari zvinodiwa kuvandudza murwiyo. Somuenzaniso, kuti mhanyisa maitiro modifiers anoshandiswa, izvo yebhasera zvidimbu zvidiki. Panyaya pigments, vanokwanisa kushandura Zvinoonekwa ari chinhu nzira ruvara kururamiswa. Kuti kuderedza mapurasitiki kugutsikana, fillers anoshandiswa hunoita zvakawanda uye isingadhuri zvigadzirwa.

Excipients angava:

• talc;
• choko;
• kabhoni dema;
• mushonga, girazi, carbon fibers.

Zvisinei, mazita aya hazvigoni kunzi kwakakwana. Polyurethane fomu kuti ibwe vane ruvara noruvara kubva chiedza tsvuku kuti shava. Kana kushandisa anokosha yokuvirisa, zvinokwanisika kuti chero ruvara.

mhedziso

Polyurethanes nhasi dzave kushandiswa zvinenge zvose okukurukura indasitiri. More zvinhu rinoshandiswa muupenyu. Somumwe vaizotibata nzvimbo anoita mvura bicomponent polyurethane. Kushandiswa nyore uye speeded basa iri kutsinga nekongiri uye purasita. Achibatsirwa polyurethane akaita zvibvire kugadzirwa duku mapurani siyana, tichigadzira uye decoration okunze, kunyange kumba.
