Kugadzirira uye hunhu hwePolyurethane semi-yakaoma foam yekakwirira-performity emagetsi emotokari.
Iyo Armrest mukati memukati memotokari chikamu chakakosha chekamuri, chinoita basa rekusundidzira uye kudhonza gonhi nekuisa ruoko rwemunhu mumota. Muchiitiko che emergency, apo mota uye pormy collision, polyurethane soft handrail uye modified pp (polypropylene) uye imwe styremele Polyurethane Soft Foam Handrails inogona kupa ruoko rwakanaka kunzwa uye yakanaka nzvimbo yekuvandudza, nekudaro ichivandudza nyaradzo uye runako rwejongwe. Naizvozvo, nekuvandudzwa kweindasitiri yemotokari uye kuvandudzwa kwezvekushandisa kwevanhu kuti zvinhu zvemukati, zvakanakira polyurethane zvinonzwika zvemaoko mumotokari zviri kuita zvakawanda uye zviri pachena.
Kune matatu marudzi ePolyurethane akapfava Handrails: High Simillence Foam, Yakazvarwa Foam uye Semi-Rigid Foam. Iyo yekunze pamusoro pekusarudzika kwekusiya mari yakafukidzwa nePVC (polyvinyl chloride) ganda, uye zvemukati ndezvePolyurethane Highes Foam. Tsigiro yePoam haina kusimba, simba racho rakaderera, uye kuderedza pakati pehuputi uye ganda rakakwana. Iyo yekuzvibata-ganda ruoko ine foam core yeganda, mutengo wakaderera, wakanyanya kuwirirana degree, uye inoshandiswa zvakanyanya mumotokari dzekutengesa, asi zvakaoma kufunga nezvepamhepo uye kunyaradza kwakazara. SERI-RIGID ARMT yakafukidzwa nePVC ganda, ganda rinopa kubata kwakanaka uye kutaridzika, uye iyo yemukati yeSemid Foam inonzwa, kupokana nekukwira, saka zvinoshandiswa zvakanyanya mukushandiswa kwemotokari yemutyairi.
Mupa iri, iyo nzira yekutanga yePolyurethane semi-yakaoma foam yemotokari yakagadzirwa, uye kuvandudzwa kwaro kunodzidziswa pane iyi hwaro.

Mhedzisiro uye Kukurukurirana
Mechanical Pfuma
By changing the ratio of polyether polyol A and polymer polyol B in the basic formula, the influence of different polyether dosage on the mechanical properties of semi-rigid polyurethane foam was explored, as shown in Table 2.
Inogona kuoneka kubva pamhedzisiro muTafura 2 iyo iyo chiyero chePolyether Polymer A kune Polymer Polyt Polyt be ine kukosha kweiyo manhamba ePolyurethane foam. Kana iyo chiyero chePolyether Polyl a Kuti Polymer Polymer BLOLL B inowedzera, elongation yekuzorora inowedzera, kuomarara kwekumanikidza kunoderedza kusvika kune imwe nhanho, uye kusimba kwesimba uye nekubvarura simba kuchinja zvishoma. Kaini yeMolecular yePolyurethane inonyanya kuve yechidimbu chakapfava uye chidimbu chakaoma, chakapfava chakapfava kubva kuPolyol uye chakaoma chikamu kubva kuCarbamate Bond. Kune rimwe divi, iyo hama yehuma uye hydroxyl kukosha kwemapolyols akasiyana, kune rumwe rutivi rwechirambidziro yebhenji the foam. Kana polyether polyol a is 80 zvikamu uye polymer Polyol B ndeye zvikamu gumi, izvo zvakaringana michina manhamba emupenga ari nani.
Kubatira pfuma
Sechigadzirwa chakakwirira chevhuru Pahwaro hwekutsvagisa pamusoro apa, kuparadzwa kwakasiyana kwakasarudzika kwakawedzerwa kuti uedze kudedera zvinhu zve foam uye ganda. Mhedzisiro yacho inoratidzwa muTafura 3.
Zvinogona kuoneka kubva kuTafura Mushure mekushandiswa kwekuwedzera 1 ne3, iyo simba remhando isina kurovedzwa ine kumwe kuwanda, uye simba rekuwedzera pane iro renyaya yemuenzaniso, uye simba rekuwedzera kwe30 Musiyano uripo pakati pekuwedzera 1 uye unowedzera 3 zvinonyanya kukonzerwa nemusiyano mukunyorovesa kwezvinhu zvemukati. Kazhinji, kuongorora iyo yakanyoroveswa yemvura pane yakasimba, iyo kona yekuwonana ndeye yakakosha paramende yekuyera mvura yemvura. Naizvozvo, kona yekubatira pakati pezvinyorwa zveganda uye ganda rapera kuwedzera maviri ekunyorova kuparadzwa kwakaedzwa, uye mhedzisiro yakaratidzwa mumufananidzo 1.
Zvinogona kuoneka kubva kuMufananidzo 1 kuti iyo yekunyepedzera kona yemhando isina kunaka ndiyo yakakura, iyo iri 27 °, uye iyo kona yeAuxiliala Izvi zvinoratidza kuti kushandiswa kwekuwedzera kwe3 kunogona kuvandudza kunyorovesa kwezvinhu zvinoumbwa uye ganda kusvika pakakura, uye zviri nyore kupararira pamusoro peganda, saka kushandiswa kwekuwedzera 3 kune simba rakakura kwazvo.
Kukwegura Pfuma
Zvigadzirwa zvechigadzirwa zvinodzikiswa mumotokari, kuwanda kwechiedza chezuva kwakakwira, uye kuita kwekukwegura ndiko kumwe kuita kwakakosha kuti polyurethane semi-yakaoma handrail foam inofanirwa kufunga nezvayo. Naizvozvo, kuita kwekukwegura kweiyo nzira yekutanga yakaedzwa uye kudzidza kwekuvandudza kwakaitwa, uye mhedzisiro yakaratidzwa muTafura 4.
Nekuenzanisa iyo data muTafura 4, inogona kuwanikwa kuti manhamba ezvekuita mafomu ekutanga akaderera mushure megumi nemaviri Iko kurasikirwa kwekuita kwemakore makumi maviri nemashanu ndeye 23% ~ 26%. Zvinoratidzwa kuti hupfu hwekuchera midziyo yeiyo formula haina kunaka, uye yekupisa yekukwira midziyo yemafomu epakutanga inogona kuve pachena nekuwedzera kirasi yeAntioxidant A kune fomula. Pasi pemamiriro ezvinhu akafanana ekuedza mushure mekuwedzera kweAndiyoxidant a, kurasikirwa kwezvinhu zvakasiyana-siyana mushure me12h yaive 7% ~ Kuderera kwezvinhu zvekuita zvinonyanya kukonzerwa neyekutevedzana kwekutenderera kwemakemikari zvakakonzerwa nemwenje wekurira panguva yekukweva kwekutanga, zvichikonzera shanduko dzakakosha muchimiro kana zvivakwa zvechinhu chepakutanga. Pane rimwe divi, kuderera kwekurongedza pabasa kwakakonzerwa nekudzikira mumakambani ezviputi pachako, nekuti iyo PVC ganda rine huwandu hukuru hwepombi, uye iyo plasticze inofamba-famba mukati meiyo nzira yekukanda okisijeni. Kuwedzerwa kweAntioxidants kunogona kuvandudza marembudzi aro ekukwegura, kunyanya nekuti antioxidants inogona kubvisa zvangogadzirwa zvemahara emahara, kunonoka kana kudzivirira iyo oxdidation maitiro eblymer, kuitira kuchengetedza zvinhu zvekutanga zvemapolymer.
Kuita Kwakakwana
Zvichienderana nemhedzisiro iri pamusoro, iyo fomati yakakwana yakagadzirwa uye zvivakwa zvakasiyana siyana zvakaongororwa. Kuita kweiyo formula kwakaenzaniswa neiyo yeiyo general polyurethane yakakwira rebound ruoko ruoko foam. Mhedzisiro yacho inoratidzwa muTafura 5.
Sezvazvinogona kuoneka kubva kuTafura 5, kuita kweiyo yakaringana semi-yakaoma polyurethane fomulula ine zvimwe zvakanakira pamusoro peiyo yakakosha uye yakafanira, uye yakakodzera kushandiswa kwekushandisa kwemaoko epamusoro-soro.
Mhedziso
Kugadzirisa huwandu hwePolyether uye kusarudza zvinokwanisika kunyorova uye antioxidant inogona kupa iyo hafu-yakaoma polyure Zvichienderana nekuita kwakanaka kweiyo foam, iyi yakakwirira-perform-polyurethane semi-yakaoma foam chigadzirwa inogona kuiswa kune emagetsi emaoko emotokari senge maoko uye matafura emidziyo.
