Acrylic plastiki zvikamu kubva kujekesa zvakajeka

Acrylic acid uye its estmer ye polymerization yePolymers yakawanikwa pamwe chete zvakataurwa Kufanana neAcrylic estuls, iyo inoenderana mapurasitiki pamwe chete inotaurwa nezvayo sepolwacrylic acid plastics, yeiyo methyl methacrylate ndiyo inonyanya kushandiswa. Polymethyl methacrylate bylevievation kodhi yePamma

Performance of PMMA

Poly (methyl methacrylate) yakaomarara, yakaoma, isina ruvara uye yakajeka uye yakajeka ye118G / CM3 pane 2%, iyo iri yakakwirira-mhando organic pachena zvinhu.

1. Mechanical Properties yePMMA

Poly (methyl methacrylate) ine yakanaka mitezo mitezo, mumashure memakiromita ekunyora, akakwira, etc., et. , asi zvakare zvishoma kupfuura polystyrene. Kanda muviri wePolymerization yePolymerizyl Polymethyl pepa rePethacrylate

Kazhinji, Simba rePolymethyl methacrylate rinogona kusvika padanho re50-77mpa, simba rinogona kusvika 90-130mpa, iyo chikamu chekumusoro kweiyi data yasvika kana kutokwira mamwe mainjiniya mapurasitiki. Denderedzwa rayo pakuzorora chete 2% -3%, saka maitiro emhando yehunhu hwepurasitiki, uye kupwanya kushushikana, asi kupwanya kupenga hakuna kufanana negirazi uye yakajairika maliganic girazi seyakapinza. 40 ℃ Ichishuwarenzi yechipiri transition, yakaenzana nerutivi rweboka reMethyl rakatanga kufambisa tembiricha, anopfuura 40 ℃, kuoma kwekunyora, kushushikana kwakavandudzwa. Kuomarara pamusoro pePolymethylmethacrylate kwakaderera, uchiita kuti zvive nekukurumidza kusvika kune abrasion.

Simba rePoly (methyl methacrylate) rine hukama nenguva yekushushikana kwekushandiswa, uye simba rinoderera sezvo nguva yekushandisa inowedzera. Zvivakwa zvePolymethylmethacrylate (yakatenderwa plexiglass) mushure mekutarisisa kweteniles kwakakosha zvakanyanya, uye notch kunzwa kwacho kunovandudzwa. Iko kupokana kwekupisa kwePolymethyl , Vicat zvinonhuwirira zvinonakidza zveanenge 113 ℃. Kupisa kupokana kunogona kuvandudzwa necoponymentizing iyo monomer ne procylene methacrylate kana bis (ester) glycol acrylate. Iko kutonhora kupokana kwePolymethyl methaacrylate zvakare murombo, uye tembiricha yerudzi rweanenge 9.2 ° C. Tembiricha yePolymethyl methacrylate zvakare iri murombo. Kugadzikana kwePoly (Methyl Methacrylate) Ndezvepakati, zvirinani pane polymaldehded kuchine huwandu hwakawanda hwekunyungudika hwekugadzirisa tembiricha. Thermal Discount uye chaiyo inopisa simba rePoly (methyl methacrylate) ndege yemapakati muPlastics, zvichiteerana 0,19,4 cm kl kg.k / 2.

2. Zvivakwa zveMagetsi zveMMA

Zvivakwa zvemagetsi zvePoly (methyl methacrylate) hazvina kunaka seyezvemapuranga asiri mapuranga uye polystyrene nekuda kwekuvapo kwedare reparty Iyo polarity yeiyo methyl ester group yeboka haina kunyanya kukura, uye polyl (methyl methacrylate) ichine yakanaka dielectric uye yemagetsi insultric. Zvakakodzera kunongedza kuti Polymethyl methacrylate uye kunyange iyo yese acrylic plassics, pasi pechiitiko cheArc, iyo nzvimbo haizoburitse carbonid nzira yekugadzirisa nzira neArc trail phenomenon. 20 【iri tembiriro yechipiri inoshandura, inoenderana nedivi reMethyl Ester Ester Boka rakatanga kufambisa tembiricha, pazasi pegumi eMethyl Ester Boka muSturising State, zvimiro zvemagetsi zvemagetsi pane mu 20 ℃ kana zvimwe ichavandudzwa. Zvivakwa zvemagetsi zveMma zvichave zvakavandudzwa kana zvinyorwa zviri pamusoro pegumi nemakumi maviri.

3. PMMA yaMakemikari uye Solvent kuramba

Poly (methyl methacrylate) inodzivirira kuDilute Acids, asi yakadzvanywa Nordroxide, . Its solubility paramende ndeye 18.8 (J / cm3) 1/2, uye inogona kunyungudutswa muHydrocarbons, Syrichlore Dichlubons, Trichloromy Dichluboni, Trichloromy Dichlemen. ita kuti ive isina kunyungudika. Poly (methyl methacrylate) ine zvakanaka kuramba kune magasi akadai se ozone uye sarufa dioxide.

4. Kubata Kwemamiriro ekunze PMMA

Poly (methyl methacrylate) ine simba rakanakisa pakukwegura, ruremu ruremu, renje riruva rakadzikira, simba rezvemisheni rakaderera, kukanganisa simba zvakare. , zvimwe zvinhu zvemuviri zvinenge zvisina kuchinjika.

5. PMMA KUTYA

Poly (methyl methacrylate) zviri nyore kupisa, kushoma oxygen index ye chete 1713.

Iko kushandiswa kwePolymethyl methacrylate pmma

Sechinyorwa chinojeka nekuita kwakanaka, polymethyl methacrylate inoshandiswa zvakanyanya mune zvinotevera zvinhu:

1. Mwenje, midziyo yemwenje, yakadai seyakasiyana emwenje yemwenje yemumba, fluorescent marambi, mota tairests, marondedzero emumugwagwa, zviratidzo zvemigwagwa.

2. Optical Girazi, sekugadzirwa kwemhando dzakasiyana-siyana dzeLenses, magirazi, maSpisms, terevhizheni screens, ma-fresnel lens, kamera lens zero.

3. Kugadzirira kwezvinhu zvakasiyana-siyana uye mita dial, chifukidziro, dial.

4. Kugadzirira kweiyo Optical fiber.

5. Commodity yekushambadzira Windows, mabhodhi.

6. Ndege cockpit girazi, ndege uye mota bulletproof glass (ine yepakati yakarukwa zvinhu).

7. Mhando dzese dzekurapa, mauto, arthectural girazi.

8. Mumunda weMicrofluidic Chip, inoshandiswa kuita microfluidic chip yakagadzirwa nePMMA.
