Nhau - Kuvhura Iyo Inogoneka yeTPEs: Strategies for Superior Scratch uye Mar Resistance

Nzira dzekusimudzira Scratch uye Mar Resistance yeTPE Zvishandiso

Thermoplastic elastomers (TPEs) ikirasi inosiyana-siyana yezvinhu zvinosanganisa hunhu hweese ari maviri thermoplastics uye elastomers, inopa kuchinjika, kusimba, uye nyore kugadzirisa. TPE dzave sarudzo yekutanga kune vagadziri vemidziyo uye mainjiniya ari kutsvaga zvinyoro, elastomeric zvinhu. Zvishandiso izvi zvinoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira mota, zvinhu zvevatengi, zvigadzirwa zvekurapa, zvemagetsi, HVAC, uye mamwe maindasitiri ekushandisa.

Classifying TPEs

MaTPE akaiswa muchikamu nemakemikari awo: Thermoplastic Olefins (TPE-O), Styrenic compounds (TPE-S), Vulcanizates (TPE-V), Thermoplastic Polyurethanes (TPE-U), Copolyesters (COPE), uye Copolyamides (COPA). Muzviitiko zvakawanda, maTPE senge polyurethanes uye copolyesters akawedzeredzwa-engineer kune yavo yavanoda kushandiswa apo TPE-S kana TPE-V ingave yakakodzera uye isingadhuri sarudzo.

TPEs dzakajairwa kazhinji dzinosanganisira musanganiswa werabha uye thermoplastic resins. Nekudaro, thermoplastic vulcanizates (TPE-Vs) inosiyana sezvo zvimedu zverabha zviri muzvinhu izvi zvakabatanidzwa kana zvizere-yakabatana kuti iwedzere kushanda.

TPE-Vs inopa yakaderera compression set, zvirinani kemikari uye abrasion kuramba, uye kushanda kwepamusoro patembiricha yakakwira, zvichivaita vanokodzera kutsiva rabha muzvisimbiso. TPEs dzakajairwa, kune rumwe rutivi, dzinopa hukuru hwekugadzira kuita kwakasiyana-siyana, dzichivabvumira kuti vagadzirirwe-yakagadzirirwa kune chaiwo maapplication, senge zvigadzirwa zvevatengi, zvemagetsi, uye zvigadzirwa zvekurapa. Aya maTPE anowanzo kuve nepamusoro pesimba rekusimba, zvirinani elasticity ("snappiness"), hukuru hwemavara, uye anowanikwa muhupamhi hwekuoma kwemazinga.

MaTPE anogona zvakare kugadzirwa kuti aenderane neakaomarara substrates sePC, ABS, HIPS, uye Nylon, ichipa iyo yakapfava-yekubata-kubata inowanikwa pane zvigadzirwa senge bhurasho remazino, maturusi emagetsi, uye zvemitambo.

Zvinetso neTPEs

Kunyangwe kuita kwavo kwakasiyana-siyana, rimwe rematambudziko neTPEs kubatwa kwavo nekukwenya uye mar, izvo zvinogona kukanganisa kukwezva kwavo kwese uye kushanda kwekuvimbika. Kugadzirisa nyaya iyi, vagadziri vanowedzera kuvimba neakasarudzika ekuwedzera anowedzera kukwenya uye mar kuramba kweTPEs.

Kunzwisisa Scratch uye Mar Resistance

Usati waongorora zvimwe zvekuwedzera, zvakakosha kuti unzwisise pfungwa dzekukwenya uye mar kuramba:

Scratch Resistance:Izvi zvinoreva kugona kwechinhu kushingirira kukuvadzwa kubva kuzvinhu zvakapinza kana zvakakasharara zvinogona kucheka kana kuchera pamusoro.
Mar Resistance:Mar resistance ndiko kugona kwechinhu kuramba kukuvara kudiki kwepamusoro uko kungasapinda zvakadzika asi kunogona kukanganisa chitarisiko chayo, senge scuffs kana smudges.

Kunatsiridza zvivakwa izvi muTPE kwakakosha, kunyanya mumashandisirwo ayo zvinhu zvinoratidzwa kuti zvirambe zvichisakara uye kubvaruka kana uko kutaridzika kwechigadzirwa chekupedzisira kwakakosha.

Nzira dzekusimudzira Scratch uye Mar Resistance yeTPE Zvishandiso

Izvi zvinotevera zvinowedzera zvinowanzo shandiswa kuvandudza kukwenya uye mar kuramba kweTPEs:

1.Silicone-Based Additives

Silicone-based additives inoshanda zvakanyanya mukusimudzira kukwenya uye mar kuramba kwe thermoplastic elastomers (TPEs). Izvi zvinowedzerwa zvinoshanda nekugadzira chigadziko chekuzora pamusoro pechinhu, kuderedza kukwesha uye nekudaro kuderedza mukana wekukwenya.

Basa:Inoshanda semafuta epamusoro, kuderedza kukweshera uye kupfeka.
Benefits:Inovandudza kukwenya kuramba pasina kukanganisa zvakanyanya ma mechanic zvivakwa kana kuchinjika kweTPE.

Zvakananga,SILIKE Si-TPV, novelsilicone-based additive, inogona kuita mabasa akawanda, akadai seaProcess additive for thermoplastic elastomers, Modifiers for Thermoplastic elastomers,Thermoplastic Silicone-based elastomers modifier, Thermoplastic elastomers inonzwa inogadzirisa.Iyo SILIKE Si-TPV Series ndeyedynamic vulcanized thermoplastic silicone-based elastomer, yakagadzirwa nehunyanzvi hwekuenderana tekinoroji. Ichi chiitiko chinoparadzira silicone rabha mukati meTPO se2-3 micron zvidimbu, zvichikonzera zvinhu zvinosanganisa kusimba, kusimba, uye abrasion kuramba kwe thermoplastic elastomers nezvinhu zvinodikanwa zvesilicone, sekupfava, kunzwa silky, UV mwenje kuramba, uye makemikari kuramba. Zvishandiso izvi zvakare zvinogona kushandiswa zvakare uye kushandiswa zvakare mukati memaitiro echinyakare ekugadzira.

RiniSilicone-Yakavakirwa Thermoplastic Elastomer (Si-TPV)inosanganiswa muTPEs, izvo zvinobatsira zvinosanganisira:

Kuvandudzwa kweabrasion resistance
Enhanced stain resistance, inoratidzirwa nekakona kadiki kekusangana kwemvura
Kuomarara kwakaderedzwa
Minimal kukanganisa pane mechaniki zvivakwa neiyoSi-TPVseries
Yakanakisa haptics, inopa yakaoma, silky kubata isina maruva mushure mekushandisa kwenguva refu

2. Wax-Based Additives

Waxes rimwe boka rezvinowedzera zvinowanzoshandiswa kusimudzira zvimiro zveTPEs. Vanoshanda nekutamira pamusoro, vachigadzira chidziviriro chekudzivirira chinoderedza kukwesha uye kunonatsiridza kurambana nekukwenya uye kuroora.

Mhando:Wakisi yepolyethylene, wakisi yeparafini, uye wakisi yekugadzira inowanzoshandiswa.
Benefits:Izvi zvinowedzera zviri nyore kuisa muTPE matrix uye zvinopa mhinduro inodhura yekuvandudza kusimba kwepamusoro.

3. Nanoparticles

Nanoparticles, senge silica, titanium dioxide, kana alumina, inogona kuiswa muTPEs kuti iwedzere kukwenya uye kuramba kwemar. Izvi zvimedu zvinosimbisa iyo TPE matrix, zvichiita kuti zvinhu zviome uye zvisarambe kukuvara kwepamusoro.

Basa:Inoshanda sesimbi inosimbisa, inowedzera kuoma uye kuoma kwepamusoro.
Benefits:Nanoparticles inogona kuwedzera zvakanyanya kukwenya kuramba pasina kukanganisa kusimba kana zvimwe zvinodiwa zveTPEs.

4. Anti-Scratch Coatings

Kunyange isiri yekuwedzera pase, kushandisa anti-scratch coatings kune zvigadzirwa zveTPE inzira yakajairika yekuvandudza kusimba kwazvo kwepamusoro. Aya machira anogona kugadzirwa nezvinhu zvakasiyana-siyana, zvinosanganisira silanes, polyurethanes, kana UV-akaporeswa resin, kuti ape yakaoma, inodzivirira layer.

Basa:Inopa iyo yakaoma, yakasimba yepamusoro layer inodzivirira kubva kumakwara uye kukanganiswa.
Benefits:Coatings inogona kugadzirwa kune chaiyo maapplication uye inopa kuchengetedzwa kwenguva refu.

5. Fluoropolymers

Fluoropolymer-based additives inozivikanwa nekunaka kwayo makemikari kuramba uye kuderera kwesimba repamusoro, izvo zvinoderedza kukwenya uye kuwedzera kukwenya kuramba kweTPEs.

Basa:Inopa yakaderera-kukweshera pamusoro inopesana nemakemikari uye kupfeka.
Benefits:Inopa yakanakisa kukwenya kuramba uye hupenyu hurefu, ichiita kuti ive yakakodzera kune yepamusoro-inoshanda maapplication.

Zvinhu Zvinokonzera Kushanda Kwezvinowedzera

Kushanda kweizvi zvinowedzera mukuvandudza kukwenya uye kuramba kwemar kunoenderana nezvakati wandei zvinhu:

Concentration:Huwandu hwekuwedzera hunoshandiswa hunogona kukanganisa zvakanyanya zvimiro zvekupedzisira zveTPE. Optimal concentrations inofanirwa kuverengerwa kudzikamisa kupikisa nezvimwe zvinhu.
Kuenderana:Iyo yekuwedzera inofanirwa kuenderana neiyo TPE matrix kuti ive nechokwadi kunyangwe kugovera uye kuita kunoshanda.
Processing Conditions:Mamiriro ekugadzirisa, akadai sekushisa uye shear rate panguva yekubatanidza, inogona kukanganisa kupararira kwezvinowedzera uye kushanda kwavo kwekupedzisira.

Kuti udzidze zvakawanda nezve seiThermoplastic Silicone-based elastomer modifiersinogona kukwidziridza TPE zvinhu, kusimudza yako yekupedzisira chigadzirwa chepamusoro aesthetics uye kuvandudza kukwenya uye mar kuramba, ndapota taura SILIKE nhasi. Inzwa mabhenefiti ekuoma, silky kubata pasina kutumbuka, kunyangwe mushure mekushandisa kwenguva refu.
