Polyester nebwe epoxy nebwe: kusafanana, zvinhu uye wongororo

Epoxy uye polyester Inogadzirwa nemasiridzi anobuda mumiti, kusawirirana chichakurukurwa munyaya ino ndezvaJehovha kirasi thermosetting. Izvi zvinoreva kuti mushure solidification muitiro vanogona havana kudzokera nemvura mamiriro. Both Formulations vane unhu hwakasiyana, izvo anosarudza chadzo. Kuti tinzwisise chinangwa izvi zvinhu zvinobatsira kuzivana naye kudzokorora epoxy uye polyester Inogadzirwa nemasiridzi anobuda mumiti.

epoxy

Epoxy anoreva zvokuvakisa ose chakaita zvokugadzirwa mavambo. In yakaisvonaka chimiro hazvina akakodzera kushandiswa sezvo vaizviita kuti yakasimba hurumende chinja haakwanisi. Kudira ari epoxy nebwe riri yebhasera zvakarurama kukura inokosha hardener.

Nokuti yakarurama kushandiswa zvakakodzera kuziva zvayakanakira nezvayakaipira ane epoxy nebwe. The nebwe iri mhando iri inoremekedzwa kuti simba rayo unhu. Zviri husingakwanisi vanotyaira makemikari zvakadai acids uye alkalis. Zvakanakira epoxy dzinosanganisira: mwero shrinkage, mukuru vapfeke nemishonga, uye rakaisvonaka mukurumari. solidification kwacho kunoitika pamusoro navanopinda tembiricha siyana, asi inokurudzirwa muupenyu span kubva +18 kusvika +25 inegumi. Hot nokudira nzira inoshandiswa zvaAtemisi yakawedzera simba anokwanisa withstanding akanyanyisa zvinorema.

Izvi mhando Inogadzirwa nemasiridzi anobuda mumiti zvaishandiswa bhizimisi uye mumba. The Kukura kwavo kushandiswa kuri yainyanya kuburikidza pakusikwa nziyo itsva optimized ehupfumi. Nokuda vaiitawo pakubhadhara akasiyana epoxy Inogadzirwa nemasiridzi anobuda mumiti uye hardeners inogona kugadzirwa kokupedzisira chigadzirwa pamwe dissimilar chaizvo unhu.

Kushandisa epoxy nebwe

Epoxy mhando nebwe anonyanya kushandiswa senzvimbo mashoko chokuedza hukawanika: huni, matehwe, simbi uye vamwe vasiri porous. mumwe sezvamunoita kwakadaro aiti ari zvemagetsi, engineering ndege. Washington City Offices, achishingaira kushandiswa kuvaka, vari rakagadzirwa epoxy. The nebwe rakashandiswa mvura uriri uye masvingo, kusanganisira zvekunze. Finished zvigadzirwa dzakagadzirwa Washington City Offices, pashure kukuya uye kubudiswa akakurumbira zvikuru munyika kushongedzwa omukati musha.

Kurapa muiti nokuti epoxy nebwe

Epoxy zvinhu ine yenhengo maviri, izvo pashure nokusanganisa ari polymerization kwacho kunotanga. Chinoumba kukonzera solidification pamusoro epoxy nebwe inonzi hardener. Zvichienderana kushandisa dzakasiyana Inogadzirwa nemasiridzi anobuda mumiti uye hardeners zvinogona kugadzirirwa zvikuru kusiyana epoxy nezvakasanganiswa.

Huwandu okurapa mutumwa ari nziyo kunogona siyana uye kunobva zvikurukuru pamusoro mugiredhi nebwe. epoxy nebwe polymerization kuita kusingarapiki, kureva uchanyangadika yave Rakasimbisa zvinhu hazvibviri.

Zviri kukanganisa kutenda kuti kana achiwedzeredza uwandu hardener nokuomesa achava nokukurumidza. Nzira inoshanda racho rikurumidze - kuwedzera kudziya musanganiswa. Kuwedzera kushanda tembiricha 10 madhigirii anogona mhanyisa muitiro ka3. Kune anokosha zvinoriumba kuti zvinangwa izvi mumusika. Panewo wemisanganiswa pamusoro epoxy, solidifying panguva yakaderera tembiricha.

Sizvo pakusarudza uwandu hardener ane tigume nokunaka rakapera chigadzirwa. Zvikurukuru zvinoderedza simba rayo uye kuramba nemakemikari. Kana shoma hardener chiri kunama kusachinja-chinja zvikamu, ane nekumwisa polymer pamusoro zvinhu pamusoro iri dzinounzwa. The kupfuura kakawanda kukura nebwe / hardener vari 1/2 kana 1/1. Usati nokusanganisa, Zvinokurudzirwa kuverenga mirayiridzo yakarurama zvinoriumba reshiyo.

polyester nebwe

mumwe nebwe kwakadaro achiumbwa kubudiswa alcohols unokudzwa. Hwaro zvinhu ndiyo polyester. kushandiswa zvokufembedzwa uye FIs yaishandiswa mhanyisa okurapa rikurumidze. Zvichienderana pokushandisa zvinhu, zvinogona kuva zvakasiyana marongerwo uye zvivako. The zvichiguma chigadzirwa anoda humwe kurapwa zvainanga tivandudze kudzivirira mvura uye UV nemwaranzi. Zvimwe bemhapemha hunowedzerawo simba zvechadenga chigadzirwa. Polyester nebwe, kusafanana epoxy, kunoratidzwa yakaderera zvemaziso ehupfumi. Asi panguva imwe chete poliefirku ine mari yakaderera, nemhaka iyo zvinhu zvikuru nevanhu.

Inogadzirwa nemasiridzi anobuda mumiti kwakadaro dzinoshandiswa kwazvo mukuvaka kuvaka, motokari, shipbuilding uye kugadzirwa mumidziyo kuti makemikari. Polyester zvinoriumba kana hwakakanyiwa girazi kuti aumbe dzakakwirira simba akakura. Nokuda kunoguma zvinhu rinoshandiswa zvaAtemisi awnings, matenga kuti zvivako uye okuvimba.

The polyester nebwe riri mune Zvinoumba hazvizivi ibwe. Made kushandisa ichi chezvinonhuwira mapurasitiki rinoshandiswa zvaAtemisi hwindo Sills, yokugezera zviruva, partitions uye decoration okunze. Polyester Inogadzirwa nemasiridzi anobuda mumiti, kusiyana epoxy, nyore staining.

The chikuru zvakanakira polyester mhando nebwe

Polyester nebwe, kusiyana epoxy, ane mukuru kushanda. Mushure nokusanganisa, magirazi akafanana anova simba unhu, runopfuura ehupfumi ari simbi. Nokuti achiomesa poliefirki kunoda hapana Mamiriro ezvinhu uye kutonhora. Basa naro vanoonekwa kuti zvishoma basa-nyanyisa, uye mashoko acho isingadhuri.

Ndoupi musiyano?

Achibvunza mubvunzo: "? Ndezvipi zviri nani, poliefirka kana epoxy", Unofanira kunzwisisa nebwe kunodiwa sei uye kupi. Zvose zvinhu vane zvayakanakira dzavo nezvayakaipira, uye yokupedzisira sarudzo kunobva ezvinhu mashandisiro, uyewo mhando pasi iyo nebwe richashandiswa.

Epoxy ane ukoshi yakakwirira, asi zviri zvikuru yakasimba. Tinazvo zvakaisvonaka namira ehupfumi kuti zvakasimba richibatanidza zvakasiyana pamusoro mamiriro. Epoxy nebwe zvakasiyana kubva polyester chigadzirwa kunyora nezvavo shrinkage, nani zvemaziso maitiro uye kuramba dzokupfeka.

Saka, kusiyana poliefirki, epoxy vanoda yakawanda nguva solidification, izvo DZEMUNHU DZINODZORA muitiro mukugadzira zvikamu izvi zvinhu. Anoshanda nebwe kwakadaro pamwe kwakawedzera kuchengeteka: kana tichishanda nemvura zvinhu zvinokosha kushandisa magiravhusi kugadzirisa zvinhu zvikukutu vanoda unomubatsira kufema. The ngozi haisi zvokuti nebwe sezvo zvakamisa hurongwa chimbuzi yakasimba mamiriro s. Kana Rakasimbisa pasi kumusoro tembiricha ezvinhu pane mukana kurasikirwa viscosity zvinhu kuti pave mamwe matambudziko pabasa.

Chii nani nebwe, epoxy kana polyester? Reviews vanoti kuti kakawanda, wokutanga unoshandiswa sechinhu namira, sezvo nzvimbo ayo akakwirira zvikuru kupfuura zvinhu zviri polyester. Mune mamwe mamiriro ezvinhu, imwe pfungwa kushandisa polyester nebwe mhando, izvo, chokutanga, achaponesa, uye chepiri hureruke basa.

Zvakanakira kushandisa poliefirki

Poliefirka kusunungura chepfu okunze, nyore kushandisa, uye unyanzvi kushanda nayo haisi kuzvireva. Murwiyo inoshandiswa yokunamisa hukawanika siyana ane unozotevera kubudiswa zvinoreva, iyo anowedzera simba. Maererano namira ehupfumi kuti epoxy poliefirka yekudyidzana akaderera, uye kurishandisa gluing hukawanika rinopikira ramangwana rakaita. Sezvo mashoko decoration zvinhu kwete rakakodzera, sezvo ane pasi zvemaziso maitiro. Kana vachisanganisa ari Zvinoumba poliefirki kushandisa shoma tiwedzere. Material anoomesa nokukurumidza, mumaawa 2-3.

The rakapedzwa chidimbu iri kwakavharwa nenyama uye husingakwanisi vachikotama. Kubvisa zvibereko polyester nebwe riri combustibility. Usamborega kushandisa polyester nebwe ive nyaya rakagadzirwa epoxy. Kuti vagadzire chigadzirwa ane epoxy zvinhu zviri nani kushandisa chete.

Sei zvakanaka kugadzirira pamusoro

The nebwe zvinofanira kutevedzerwa chete panguva pre-kunyatsogadzirira penyika. Danho rokutanga rinoitwa vachishandisa solvent degreasing. Mushure dzichibvisa tsvina uye girisi pakuonekwa kwacho rinoitwa. Sezvo zvinhu pamusoro pamwe sandpaper kana rinokosha chokushandisa hwaputswa topsheet. Zvadaro, mumwe muitiro achibvisa guruva. Zvadaro, chikumbiro zvinobvira kutanga kushanda chikamu.

tsaona dziviriro

Kuti varege kukonzera kukuvara kana tichishanda Inogadzirwa nemasiridzi anobuda mumiti uye hardeners, zvakakodzera kutora kufadza matanho okuzvidzivirira. Kutadza kutevedza mitemo nyore kunogona kukonzera kukuvara ganda, kutsva kana zvemapapu kushanda vachivavhiringidza kana kushanda epoxy kana polyester Inogadzirwa nemasiridzi anobuda mumiti. Features yakachengeteka kana kushanda makemikari:

• Usashandisa midziyo dzaizopiwa pakubika.
• manipulations All kunofanira kuitwa zvipfeko chaiyo uye magiravhusi. Asati kushanda ruoko sunscreen anofanira kutevedzerwa. Makorari pamusoro apera zvigadzirwa rinoitwa munyika unomubatsira kufema uye anokosha magirazi.
• Kana ari nebwe wakawira ganda zvinofanira kusukwa sipo pasina kunonoka kana wakachena doro.
